Device logcat (Pixel 6 Pro / Android 16) showed audio_service throwing
on every state broadcast:
java.lang.IllegalArgumentException: You must specify an icon resource
id to build a CustomAction
at com.ryanheise.audioservice.AudioService...
The #57 MediaControl.custom favorite makes audio_service build a
PlaybackStateCompat.CustomAction whose icon id resolves to 0 on real
builds; the exception aborts the ENTIRE media notification, so nothing
posts to the tray or the watch (emulator tolerated it). Not a
permission / PathParser / FGS issue — POST_NOTIFICATIONS was verified
granted. Pre-#57 there was no CustomAction, matching the regression.
Remove the custom favorite control; the notification is rebuilt with
only the standard transport controls (audio_service ships their icons).
customAction handler / refreshFavoriteControl left as harmless no-ops
to minimise churn. Like/favorite remains in-app + lock screen.

Device-surfaced on physical Android 13+ (worked on emulator):
A) The media notification never appeared because the app never
requested POST_NOTIFICATIONS at runtime — the manifest declares it
and the foreground service is correct, but Android 13+ denies it by
default until asked. Add permission_handler ^12.0.1 and request
Permission.notification once at startup (post-first-frame,
Platform.isAndroid-guarded; no-op on <13 / once decided).
B) When the #52 idle/dismiss teardown nulled mediaItem while the full
NowPlayingScreen was open, it stranded the user on an empty
"Nothing playing." Scaffold. Now post-frame maybePop() so it
auto-minimizes (the mini bar is already gone).

Fast-follow of #54. After the #52 idle/dismiss teardown, pressing play
on a headset / watch / lock screen did nothing (handler.play() was just
_player.play() with nothing loaded; the handler is Riverpod-agnostic).
- audio_handler: _resumeHook + setResumeHook(); play() is now async —
when mediaItem == null and a hook is set it awaits the hook (which
restores + plays) and returns, else _player.play()
- resume_controller: extract shared _loadAndRestore() (bool); _restore()
keeps the paused launch path; new resumeFromMediaButton() restores
then starts playback; start() registers it via setResumeHook
Recursion-safe (post-restore mediaItem != null so the re-play hits
_player.play()); no-op when nothing to resume / auth missing / a
session is already active.

_handlePlaybackError silently skipped a dead track (404 / decoder /
EOS / network drop) with only a debugPrint, hiding the signal that
tells a broken track from a flaky app.
- audio_handler: _playbackErrors broadcast stream; emit the failing
track title (mediaItem.value?.title — correctly mapped post-#49)
before the skip/pause
- playback_error_reporter (new): global scaffoldMessengerKey +
reporter that buffers, 2s-debounces, and coalesces bursts into one
SnackBar ("Couldn't play X — skipping" / "Skipped N unplayable
tracks")

Adds a heart action to the media notification implemented as a custom
control + customAction handler — NOT setRating, which is broken
upstream (audio_service #376: onSetRating never fires from a
notification tap) and previously blanked the Pixel Watch.
- res/drawable/ic_stat_favorite{,_border}.xml: white 24dp vector hearts
- audio_handler: favorite MediaControl.custom in _broadcastState
(icon/label toggle by LikeBridge state; kept out of
androidCompactActionIndices so compact/lock + Wear transport are
unchanged); customAction override (Future<dynamic>, matches base)
toggles the like then re-broadcasts; refreshFavoriteControl()
- player_provider: cascade refreshFavoriteControl into the likedIds
listener so liking from TrackRow/kebab/SSE flips the notification heart
Reliable on phone notification + lock screen; Wear/Auto display of a
non-transport custom action is platform-dependent (not a bug).

_broadcastState only set updatePosition on transitions, so the lock-
screen / Wear / Android Auto scrubber jumped in chunks (the in-app bar
uses positionStream and was fine). Add _positionBroadcastTimer: a 1s
periodic PlaybackState re-broadcast while actively playing so
updateTime/updatePosition stay fresh and external surfaces interpolate
smoothly. Idempotent (driven from _broadcastState, which the tick
itself calls — guarded against pile-up), cancelled when not playing
and in stop(). 6a: the notification progress bar now advances since
MediaItem.duration was already set.

The #52 teardown clears the session when idle/dismissed, so the
headset / lock-screen play button had nothing to resume and the user
lost their place.
- track.dart: toJson() (round-trips fromJson)
- db.dart: CachedResumeState single-row snapshot, schema 9->10 + migration
- audio_handler.dart: queuedTracks getter

- resume_controller.dart: restores last snapshot paused on launch;
persists {source,index,position_ms,tracks} debounced on track
change / pause and immediately on app teardown; never clobbers the
saved snapshot when the queue is empty so a teardown stays
recoverable; restore gated on auth + no active session
- app.dart: wired into postFrame

The Flutter client had no audio_session integration, so it didn't pause
for phone calls / other media, didn't duck for navigation prompts, and
kept blasting the phone speaker when earbuds were unplugged.
Add audio_session ^0.2.3 and configure AudioSessionConfiguration.music()
in MinstrelAudioHandler (best-effort, fully try-caught):
- becomingNoisy -> pause (no speaker blast on unplug/BT drop)
- interruption begin: duck -> lower volume; pause/unknown -> pause,
remembering whether we were actively playing
- interruption end: duck -> restore volume; pause -> resume only if we
paused it and the session isn't torn down (guards the idle-teardown
-during-long-call edge; re-init is resume-last-session territory);
unknown -> no auto-resume

Nothing drove the audio_service session to a terminal state and the
notification is configured ongoing, so the Wear tile / lock screen /
notification lingered on a stale paused track indefinitely.
- stop() override: pause, broadcast idle, clear queue/mediaItem, then
super.stop() so the foreground service + notification (and watch tile)
tear down; in-app mini bar collapses in lockstep.
- onTaskRemoved(): keep playing if audio is active (standard media
behaviour), otherwise stop so a dismissed-while-paused app doesn't
leave a stale tile.
- 5-minute idle timer armed while paused or on a finished queue,
cancelled on resume / new queue, re-checked at fire time.

player: setQueueFromTracks fast-starts a single source at player-index 0
while the full queue is broadcast, so the transient currentIndexStream→0
emission clobbered the correct mediaItem with queue.value[0] (the first
track). Mini bar / playlist marker pinned to the wrong track until a
later index event (~the "passive ~30s recovery"). Track a logical-index
base so the player→queue mapping stays correct during the fill window;
also fixes the latent forward-fill auto-advance off-by-base.

Flutter half of offline-replay capture. Play events no longer
fire-and-forget: the reporter now tracks each play as a completed
unit (track, original start time, source, duration reached)
independently of connectivity.
- EventsApi.playOffline: single timestamp-preserving call → the new
/api/events play_offline (47aa178).
- MutationQueue: new play.offline kind + handler (EventsApi).
- PlayEventsReporter rework:
- _beginTrack captures start context + fires live play_started;
the server id is adopted only if it lands while still on-track.
- position progress gated on the tracked track id so a track
change can't clobber the finishing track's last values.
- _closeCurrent: if a server id registered, attempt the live
ended/skipped and fall back to the offline queue on failure; if
no id (offline start) enqueue the completed play directly. The
server applies the canonical skip rule, so the offline payload
only carries duration.
- app paused/detached closes durably via the queue (survives a
process kill; a teardown POST would not).
Result: listening to cached tracks fully offline now records
history / recs / scrobble / #415 rotation once back online, with
the original timestamps. Web stays best-effort by standing
occasional-use scope.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The Flutter client previously reported NO plays — mobile listening
never reached play_events, so history, recommendation scoring,
ListenBrainz scrobbles, and #415 rotation all missed mobile entirely.
Operator chose to close that gap properly as part of Stage 3.
New:
- EventsApi (api/endpoints/events.dart): play_started/ended/skipped.
- PlayEventsReporter (player/play_events_reporter.dart): state
machine over (track id, playing) mirroring the web dispatcher.
Persists an opaque client_id in secure storage. Deliberate
divergence from web: a track change inside a queue is classified
ended-vs-skipped by whether the prior track reached ~its duration
(3s tolerance), instead of web's blanket "track change = skip"
which would mark every naturally-finished in-queue track a skip
and dilute recommendation skip-ratios — the exact failure mode
that motivated doing this properly. Fail-safe: no-ops when there's
no audio handler (tests / no-audio env). App-lifecycle paused/
detached closes an open row as a best-effort skip (web pagehide
parity). Wired in app.dart postFrame.
- PlaylistsApi.systemShuffle(variant): GET the rotation-aware order.
Wiring:
- audio_handler: _queueSource carried through setQueueFromTracks
(source param); preserved across internal skipToQueueItem rebuild.
- player_provider.playTracks: source param → setQueueFromTracks.
- PlaylistCard: system playlists fetch systemShuffle and play as-is
tagged with source (no client shuffle — server already ordered).
- playlist_detail_screen: header Play + per-track tap tag source for
system playlists so rotation advances from any entry point.
Known/flagged separately: the web dispatcher likely has the same
false-skip-on-advance issue; not fixed here to keep #415 scoped and
clients' wire behavior comparable.

Closes Fable #412 (For You force-refresh on play) and #413
(shuffle-on-play default for system playlists).
Web (PlaylistCard.svelte + player/store.svelte.ts):
- Drop the refreshForYou() call from the play handler. The daily
03:00 user-local snapshot is what plays now. Stops burning server
compute on every press and stops swapping the playlist out from
under the user.
- Generalize the kebab affordance to render for any system playlist
(was Discover-only). Adds "Refresh For You" as an explicit
replacement so users can still force a regen when they want one.
- Extend playQueue(tracks, startIndex, { shuffle? }) to Fisher-Yates
the queue when shuffle:true. PlaylistCard passes shuffle:true for
any non-null system_variant.
Flutter (player_provider.dart + playlists/widgets/playlist_card.dart):
- playTracks now accepts shuffle:bool. When true, picks a random
starting index and enables AudioServiceShuffleMode.all after
setQueueFromTracks. PlaylistCard passes shuffle:playlist.isSystem.
User playlists keep linear order. Detail-screen play buttons are
unchanged for now (follow-up if user requests).

Four related fixes to the player flow that together remove the
audio↔UI lag on track change:
1. **Prefetcher pre-warms covers + palette for the next N tracks.**
The existing prefetcher pinned audio files only. When auto-advance
landed on the next track, the cover bytes were cold → mediaItem
broadcast with artUri=null → now-playing screen stalled in
_scheduleSwap awaiting precacheImage of a file that didn't exist
yet. Each upcoming queue item now also fires
AlbumCoverCache.getOrFetch (writes bytes to disk so _toMediaItem's
peekCached returns the path) and AlbumColorCache.getOrExtract
(memoizes the dominant color). Both fire-and-forget; idempotent
if already cached.
2. **AlbumColorCache.peekColor sync getter** so the now-playing
fast-path can read the memoized color without awaiting a Future.
3. **_scheduleSwap fast path** when cover bytes + palette are
already cached (the common in-queue auto-advance case): commit
_displayedMedia / _displayedDominant synchronously in setState
without awaiting. The async preload remains as the slow-path
fallback for genuine cold cache. This is what closes the gap
the user reported: "art is loading and metadata hasn't updated
but the new song is playing."
4. **setQueueFromTracks: build source before broadcasting queue /
mediaItem.** Previously we broadcast immediately for snappy UI;
if _buildAudioSource threw, the UI showed the new track while
the player held the old source. Now: build first, broadcast
only on success. Source build is sub-100ms on warm cache so the
tap response cost is imperceptible. _suppressIndexUpdates is set
around setAudioSources + broadcast so a transient currentIndex
emission can't cross-broadcast the OLD queue's entry at the NEW
index.
5. **playbackEventStream error handler skips past failing tracks.**
Previously errors only logged. The player would go silent on a
404 / decoder failure but mediaItem stayed on the failed track —
user saw "now playing X" with no audio. Now seekToNext on error;
if at queue tail, pause cleanly so PlaybackState reflects idle.
Pixel Watch 2 stopped showing controls entirely after v2026.05.13.3's
MediaSession expansion. Reverting the additive pieces:
* systemActions back to the original 5 (play / pause / skipPrev /
skipNext / seek). stop, skipToQueueItem, setShuffleMode,
setRepeatMode, setRating removed.
* controls list back to skipPrev / play|pause / skipNext (no stop).
* stop() override removed — let BaseAudioHandler default apply
(probably needs to be a no-op for the MediaSession to stay alive
through certain lifecycle events that audio_service triggers
internally; the override was actually halting the session).
* MediaItem.rating no longer set in _toMediaItem. The Android
MediaSession.setRating() path requires setRatingType(RATING_HEART)
to actually expose to controllers, and audio_service doesn't
surface that config knob — broadcasting an unanchored rating
appears to make Wear OS reject the session entirely.
Kept in place:
* skipToQueueItem override — still needed for QueueScreen's direct
handler call (not routed through MediaSession actions).
* setRating override + LikeBridge wiring — harmless if never
invoked, and lights up automatically if we figure out how to
configure the rating type later.
* AlbumCoverCache.peekCached for sync artUri seed — that part
worked, and the failure mode would be a missing cover, not a
rejected session.
Watch should come back to its previous "sometimes works" state from
v2026.05.13.2 (basic controls only). Getting past that needs proper
MediaSession config that audio_service either doesn't expose or
requires platform-channel work.
External media controllers (Android Wear, Auto, Bluetooth dashes,
lock-screen widgets) consume the audio_service MediaSession and
silently no-op on any action that isn't in the handler's
systemActions set. Several handler methods were already implemented
but never advertised, plus stop() defaulted to a no-op — which
matched user reports of "media controller on the watch sometimes
works but doesn't play nice with Minstrel."
This patch lines the advertised surface up with what the handler
actually implements + wires a native heart-rating button.
**Expanded controls + systemActions:**
- Added MediaControl.stop to the expanded controls list.
- systemActions now also enumerates stop, skipToQueueItem (override
shipped in v2026.05.13.1), setShuffleMode, setRepeatMode, and
setRating. Without these in the set, Android 13+ drops the
corresponding callbacks from external surfaces.
**stop() override:** halts _player and dismisses the foreground
notification via super.stop(). Default just flipped processingState
to idle without releasing the audio session — external surfaces
treated that as "paused forever".
**setRating wiring (native heart-button protocol):** new LikeBridge
adapter passes through configure() carrying toggleTrackLike +
isTrackLiked closures over LikesController and likedIdsProvider.
- setRating override flips the like through the bridge and re-emits
mediaItem so the watch's heart icon updates immediately.
- _toMediaItem populates MediaItem.rating on every track change so
the right filled/outlined heart shows on track-A → track-B.
- PlayerActions ref.listen on likedIdsProvider calls
refreshCurrentRating so toggling a like from TrackRow / kebab /
another device (SSE) also keeps the watch icon in sync.
**artUri seed on first broadcast:** AlbumCoverCache.peekCached
returns the file path synchronously when the cover is already on
disk. _toMediaItem uses this so warm-cache tracks broadcast with
artUri populated from the first frame — external controllers see
the cover immediately instead of waiting for the later async
_loadArtForCurrentItem path. Cold-cache tracks fall through to that
path unchanged.
Regression from v2026.05.13.2's load-then-swap rewrite. _displayedMedia
only got populated by the ref.listen callback on mediaItem changes,
but ref.listen doesn't fire on initial subscription — it only fires
on transitions after the listener is registered. So opening the full
player while a track was already playing left _displayedMedia null
and the screen rendered "Nothing playing." even though the mini bar
showed a live track.
initState now reads the current mediaItem synchronously and seeds
_displayedMedia immediately (and _displayedDominant from the color
provider's cached value when available). A post-frame
_scheduleSwap(current) runs to ensure the cover bytes are decoded
and dominant color resolved when the user opens the player to a
track whose album hasn't yet been color-extracted in this session.
Previous fixes layered AnimatedSwitcher fades on top of a race: the
audio_handler broadcasts MediaItem twice on every track change
(bare metadata first, then with artUri once AlbumCoverCache resolves)
and the image bytes themselves decode asynchronously after the
widget mounts. The fades just smeared the resulting placeholder
flash without addressing the underlying ordering.
Rewrite the decision process around "load first, then swap":
**Mini player** (rapid change is acceptable per operator preference):
- Drop AnimatedSwitcher entirely
- PlayerBar becomes stateful, holds the most-recent non-null artUri
- Builds the child MediaItem with artUri = currentArtUri ?? _lastArtUri,
so the previous cover stays visible across the null-artUri gap and
the new cover snaps in the moment its artUri arrives
**Full player** (operator wants the image fully loaded before any
visible change):
- Introduce _displayedMedia + _displayedDominant state
- ref.listen on mediaItemProvider schedules a preload for each new
track id (and for the artUri-bearing rebroadcast on the same id)
- _scheduleSwap awaits precacheImage on the file:// artUri AND
awaits albumColorProvider's future for the dominant color
- Only then setState flips _displayedMedia + _displayedDominant in
one frame — cover, title, gradient all advance atomically
- Drop the per-element AnimatedSwitcher wrappers; the backdrop
AnimatedContainer still tweens between successive dominant
colors so the gradient transition is smooth, not snap
Concurrency: rapid skips drop stale preload completions via
_pendingPreloadId. Decode/color failures fall through to the
previous dominant + the ServerImage/error-builder fallbacks.
Two related "snap in" effects on the now-playing screen:
1. **Album art snapped in after the fade.** AnimatedSwitcher cross-
fades the new _AlbumArt over 300ms, but FileImage's bytes weren't
decoded yet — the widget was visually empty during the fade and
the cover landed abruptly after. precacheImage on the new file://
artUri pre-decodes the bytes so by the time AnimatedSwitcher
mounts the new tile, the cover paints synchronously inside it.
The cross-fade now carries real content end-to-end.
2. **Backdrop color snapped in.** albumColorProvider.family is
loading for the new id during the track-change moment, so
dominant fell back to fs.obsidian; AnimatedContainer tweened to
obsidian and then snapped to the resolved color a beat later.
_NowPlayingScreenState now holds _lastDominant across builds:
while extraction for the new id is loading, the gradient stays
on the previous album's color, then animates straight to the
new one once it resolves. No intermediate obsidian stop.
Net effect: track changes feel like a single smooth transition
instead of fade-out → blank → snap.
Audio handler broadcasts MediaItem twice on every track change:
once with artUri=null (the new track's bare metadata), then again
with artUri pointing at the AlbumCoverCache file once the cover
lands on disk. The mini player's cover element was rebuilding in
place: previous track's image → slate placeholder → new track's
image. That flash is the flicker reported on the v2026.05.13.0 build.
AnimatedSwitcher around the cover (180ms crossfade) keyed by the
artUri value makes the swap a smooth crossfade instead of a visible
snap. The Hero parent stays — its tag is stable across track changes
so the mini→full bar expansion animation keeps working unchanged.
Two bugs in the audio handler caused the playback issues seen on the
v2026.05.13.0 build:
1. **Queue button on the now-playing screen did nothing.** MinstrelAudio
Handler never overrode skipToQueueItem, so taps in QueueScreen fell
through to BaseAudioHandler's empty default. The queue UI updated
nothing because the handler did nothing. Now overridden: rebuilds
the source list via setQueueFromTracks(_lastTracks, initialIndex)
so the targeted item plays cleanly even when its source hadn't been
built yet by the background fill.
2. **Tapping a song in a playlist let the previous track bleed through
until the new source finished building.** setQueueFromTracks awaits
_buildAudioSource before swapping the player's source list, and
that wait can be a few hundred ms on a cache miss. During the wait
the old source kept playing while the mini player UI had already
flipped to the new title/artist. Now pause()ing the player at the
start of setQueueFromTracks silences the old source the moment the
user taps.
Also stashes the most recent TrackRef list as _lastTracks so
skipToQueueItem can reconstruct sources without having to peek into
just_audio's internal source list.
Slice 1 of the cover-caching pass. The previous Image.network /
NetworkImage path only cached covers in memory, so a scroll-off + scroll-
back or an app restart re-downloaded every tile from the server. Swap
to cached_network_image so bytes land on disk (path_provider temp dir,
URL-keyed) and survive both.
Sites migrated:
- ServerImage (all /api/*/cover usage — home grid, library, playlist,
artist/album detail headers)
- DiscoverScreen Lidarr suggestion thumbnails
- PlayerBar mini cover (HTTPS branch; file:// branch unchanged since
AlbumCoverCache files are already on disk)
Auth header forwarding preserved via httpHeaders. Fade-in disabled so
populated grids paint instantly on cache hit.
Slice 2 (pre-warm during sync) builds on this same cache manager.
Two issues caught by flutter analyze --fatal-infos:
- dart:ui import in album_color_extractor.dart was redundant because
flutter/painting re-exports the Color it provides. Dropped.
- valueOrNull isn't on AsyncValue in this Riverpod version (the
AsyncValue<Color?> nesting may also have confused the resolver).
Switched to asData?.value which always returns the wrapped value
on AsyncData and null on Loading/Error.
(palette_generator's "discontinued" warning is non-fatal informational
in pub; CI didn't fail on it. The package still works; alternative
swaps deferred until it actually breaks.)

Three of the four locked items (1, 2, 4); item 6 (swipe-tabs) stays
deferred until server-side lyrics ingestion exists.
1. Dominant-color gradient backdrop. New album_color_extractor.dart
wraps the existing AlbumCoverCache: extracts the dominant color
via PaletteGenerator over the local file, caches in-memory keyed
by album_id. Top 55% of the screen carries the color (0.55 alpha
→ fs.obsidian) so controls below stay legible. AnimatedContainer
tweens the gradient across track changes.
2. Hero transition for cover art (mini bar → full screen). Stable
kPlayerCoverHeroTag (not media.id keyed) so the transition works
regardless of what's playing and isn't racy if media swaps mid-tap.
flightShuttleBuilder renders the destination's Hero widget for the
whole flight, which reads as a clean grow rather than a swap.
4. Crossfade on track change. AnimatedSwitcher around the album art,
title, and artist+album text block, all keyed by media.id so the
switcher fades between old and new on each track-change rebuild.
Pairs with the AnimatedContainer gradient so the whole "what's
playing" zone changes in lockstep.
palette_generator: ^0.3.3 added.

Two unrelated issues, batched.
Full-player kebab → "Go to album/artist" still crashed with
_debugCheckDuplicatedPageKeys despite the prior onBeforeNavigate
fix. Cause: pop() and push() ran in the same frame, so go_router's
page-key reservation table briefly contained both /now-playing AND
the destination shell-child, tripping the duplicate-key assert.
Refactor: replace onBeforeNavigate with onNavigate(path), where the
host receives the path AFTER the sheet pops and owns the
navigation entirely. The full player wires:
onNavigate: (path) async {
await Navigator.of(context).maybePop();
if (context.mounted) GoRouter.of(context).push(path);
}
Awaiting the pop guarantees /now-playing is fully gone from the
navigator's page list before the push starts.
Mini player + track rows + everywhere else use the default (no
onNavigate) path that does context.push(path) inline — they're
already inside the ShellRoute, no race possible.
Restored alwaysRefresh: true on artistAlbumsProvider. Dropping it
in the cache-loop fix had a side effect: if drift's cachedAlbums
held only a subset of an artist's albums (user previously visited
just one album by them), the artist detail page rendered that
partial list forever — provider only fetched on empty drift, never
on partial drift. The metadata prefetcher only mass-warms
artistProvider (single row), so re-enabling SWR on artistAlbums
won't recreate the storm.
Same root cause as the /queue duplicate-page-key crash: /now-playing
is a top-level route (lives outside the ShellRoute), but
/artists/:id and /albums/:id are shell-children. Pushing a shell-
child from a top-level route makes go_router attempt to mount a
second ShellRoute on top of the active one, leaving navigation in a
broken state. The mini player works because it's already inside the
shell.
Add an optional onBeforeNavigate callback to TrackActionsSheet
(forwarded through TrackActionsButton). When set, fires after
sheet.pop() and before context.push() of the destination route.
Wire the full player's TrackActionsButton with onBeforeNavigate:
() => Navigator.of(context).maybePop() so /now-playing dismisses
itself before the detail route is pushed. Result: clean navigation
into the destination, mini player visible underneath as expected.
Mini player keeps the default (no callback) since it's already in
the shell.
The lazy source-build commit (1ddde12) introduced a race: when the
user taps play on a new track while a previous queue's
_fillRemainingSources is still working, the stale fill keeps
calling _player.addAudioSource() on the new player state — appending
old-playlist tracks into the new queue and confusing the player into
the "locked to one song" symptom.
Fix: queue-generation counter. setQueueFromTracks bumps
_queueGeneration first thing; the background fill captures its gen
at start and aborts before any further player mutation if a newer
queue has taken over. The previous play() never gets to mutate the
new player state.
Also resets _suppressIndexUpdates at the start of every
setQueueFromTracks (defensive — covers the case where a prior
backward-fill bailed on its gen check before reaching `finally`)
and only releases the flag in finally if we're still the active
gen.
Symptoms this should resolve:
- "locked to one song" after rapid play taps
- Late `play() returned 73189ms` lines indicating a previous
hung play() call finally resolving and stepping on current state
- Player stuck in odd processingState after queue swaps
Two unrelated wins as a single batch.
Flutter — lazy source building in setQueueFromTracks:
Today: Future.wait builds all N AudioSource objects (drift queries +
LockCaching ctor) before the player can call setAudioSources →
play(). Measured at 83ms for a 25-track playlist, on top of the
~285ms initial-source preload.
New flow: build only the initial source, hand it to setAudioSources
([initial], initialIndex: 0) so play() can start, then background-
fill the rest. Forward direction (skipNext targets) added via
addAudioSource. Backward direction (skipPrev) inserted at index 0..
initialIndex-1 with _suppressIndexUpdates true so the unavoidable
currentIndex shifts don't push the wrong MediaItem onto the stream.
Saves the up-front source-build wait — tap-to-audio for long queues
should drop by ~80-100ms even on cache hits.
Server — Cache-Control on the three byte-serving endpoints:
- /api/albums/{id}/cover: max-age=86400, must-revalidate. Covers
change rarely (re-scan, MBID enrichment); a day of cache is safe
and skips conditional GETs for the bulk of a session.
- /api/playlists/{id}/cover: max-age=300, must-revalidate. Collages
recompute when contents change; short enough for edits to feel
fresh, long enough to skip repeat fetches during a session.
- /api/tracks/{id}/stream: max-age=31536000, immutable. Track bytes
are immutable for a given id (scanner re-indexes by file_path; new
files get new ids). LockCachingAudioSource on the Flutter side
already disk-caches, but proper headers let it skip even the
conditional 304 on repeat plays.
Tap→audio measured at ~370ms — that path's fast. Real symptom: a few
seconds of audio, then silence with no event surfaced to Flutter.
ExoPlayer is failing/completing somewhere and we have no log to act
on.
Three changes, all log-only:
- Add onError to playbackEventStream so stream failures (404, range-
request bugs, decoder errors, network drops) print instead of
silently halting playback.
- Subscribe to playerStateStream and log playing + processingState
on every transition. Silent stops will now show as a state shift
to completed / idle / buffering with no resumption.
- Subscribe to processingStateStream separately to catch fine-grained
state transitions ExoPlayer reports between source advances.
After hot-restart, tap-then-go-quiet should produce a sequence we
can read — most likely either "processingState=completed" partway
through (server returning premature EOS or wrong Content-Length) or
a thrown error from ExoPlayer's source-loading path.
CI fixes:
- artist_detail_screen.dart: drop unnecessary foundation import (debugPrint
comes from material) and unused metadata_prefetcher import.
Playback timing visibility (so we can stop guessing where the lag
lives):
- playTracks now logs serverUrl / token / configure / setQueue /
play() returned, each stage in milliseconds. The next time you
tap play, we'll see exactly where the seconds go.
- setQueueFromTracks adds two more measurements: total source-build
time across all tracks, and setAudioSources duration.
Small concrete win:
- audio_handler caches the application cache dir path on first use
(already cached in _maybeRegisterStreamCache; now also used in
_buildAudioSource for the LockCachingAudioSource path). One less
platform channel hit per track on cache-miss queue builds.
Once we see real numbers we can decide whether the fix is to build
sources lazily (initial source first → play → background-add the
rest), pre-warm the audio handler at app start so playTracks skips
serverUrl + token reads entirely, or something else.
Closes the gap where LockCachingAudioSource wrote files to disk but
never told AudioCacheManager about them — meaning evict() couldn't
reclaim stream-cached files when usage exceeded the cap, only
explicitly-pinned downloads.
Wire just_audio's bufferedPositionStream as the "download complete"
signal: when bufferedPosition reaches duration (with 200ms slack for
header bytes), look up the on-disk file at the LockCaching path,
read its size, and insert an audio_cache_index row via the new
AudioCacheManager.registerStreamCache(). Source defaults to
incidental so stream-cached tracks are first to be evicted under
pressure.
Dedupe via _streamCacheRegistered Set so we don't hit drift on every
~200ms buffered-position emit. Cache the application cache dir path
on first use for the same reason.
Eviction now sees the full set of files on disk; usageBytes() (which
already walks the dir) and evict() (which reads the index) are
finally consistent for stream-cached tracks. Pinned tracks keep
their existing manual-download flow unchanged.
Move shuffle / repeat / queue out from below the play controls and
combine with the like + kebab into a single row sitting just above
the seek bar. Title row drops back to title-only (truly centered now,
no Stack needed since nothing competes for the row's right edge).
Layout order is now: art → title → artist → album → [shuffle, repeat,
queue, like, kebab] → seek → prev/play/next.
The "queue" icon in the top-right of the AppBar stays for now —
redundant with the new row but matches what users have already
muscle-memoried for opening the queue from any player state.
- artist_detail_screen.dart missed an `import '../models/artist.dart'`
for the ArtistRef seed parameter; analyze flagged undefined_class.
- radio.dart + player_provider.dart doc comments wrapped URL
parameters in <...> which lint reads as HTML. Switched to backticks.
Full player title is now centered absolutely via a Stack: title with
horizontal padding equal to the actions cluster width sits at the
optical center, while LikeButton + TrackActionsButton are pinned to
the right edge with Positioned. Fixed-height SizedBox(32) keeps the
row stable when the title wraps to a single ellipsized line.
Three issues, all related to the player surface:
1. Player UI didn't update on track change. audio_handler's
_onCurrentIndexChanged only kicked off the cover load — it never
pushed the new MediaItem onto the mediaItem stream. Title/artist/
cover stayed pinned to whatever setQueueFromTracks(initialIndex:)
set on first play. Now the listener pushes queue[idx] when the
index changes.
2. Player kebab "Go to artist" 404'd while the same item from
MostPlayed worked. Same TrackActionsSheet for both, but the
player's _trackRefFromMediaItem was hardcoding artistId: ''
because audio_handler's _toMediaItem never stashed it in extras.
Stash artist_id alongside album_id; player_bar +
now_playing_screen read it back. Both kebabs now navigate.
3. "Start radio" didn't exist on Flutter even though the server has
/api/radio?seed_track=<id>. New RadioApi (lib/api/endpoints/
radio.dart) wraps the endpoint; PlayerActions.startRadio(trackId)
fetches + plays the result via the existing playTracks path.
New menu item between "Add to playlist" and the divider above
"Go to album", calls startRadio with a snackbar error fallback.
Update banner showing on identical versions:
- pubspec.yaml was stuck at the placeholder 0.1.0+1, so
PackageInfo.version returned "0.1.0" while the server reported the
actual release tag (e.g. "2026.05.10.1"). Comparison correctly said
"newer" → banner always showed.
- Bump pubspec to 2026.05.11.0+1 so the local default matches the
release cadence even before CI overrides it.
- Update flutter.yml release step to pass --build-name="${TAG#v}" so
every tagged APK reports the tag as its PackageInfo.version. Future
releases stop drifting from pubspec.
- Rewrite isVersionNewer to do component-wise int comparison with
zero-padding: pub_semver.Version.parse rejects 4-part date versions
like "2026.05.10.1", at which point the old code fell back to
string inequality and treated "2026.05.10" as newer than itself
vs "2026.05.10.0". Drop the pub_semver import (no longer used).
Lock-screen play/pause not responding:
- PlaybackState only listed MediaAction.seek in systemActions, which
on Android 13+ means tapping the lock-screen play/pause button
doesn't route back to the AudioHandler. Add play, pause,
skipToNext, skipToPrevious to the set.
- Add androidCompactActionIndices: [0, 1, 2] so the compact
notification view explicitly maps the three buttons.
Album art being smaller than the lock-screen frame is upstream of
this commit — the cover-cache writes whatever pixel dimensions the
server returns. If the server's /api/albums/<id>/cover returns small
thumbnails for these albums, the lock screen renders them at that
size. Worth a separate look at the server cover-emit path.
Move the like + kebab buttons out of the title row and place them as
siblings to the title/artist column. Row's default crossAxisAlignment
centers them against the row's full 48dp height (set by the album
art), so visually they sit at the vertical center of the title+artist
block instead of being pinned to the title baseline.
Width stays 32dp each — horizontal footprint matches what we had.
Bumped icon size 18→20 since they have more vertical space to occupy.
Image with width+height but no fit paints the source at its intrinsic
resolution inside the box. The cover-cache thumbnails are smaller
than 48dp, so the art rendered as a tiny inset in the slate box
instead of filling it. Cover stretches/crops uniformly to fill.
Why the seek bar appeared frozen: it was reading
PlaybackState.updatePosition, which audio_service only updates on
event transitions (play/pause/buffer/seek). Between events it sits
unchanged, so the bar only jumped at intervals.
Expose just_audio's positionStream (~200ms cadence) from the audio
handler, wrap as positionProvider, and read that in both the mini bar
and the full player. Now the bar advances continuously while playing.
While we're here: spread the full player's vertical layout per
operator — gap to seek 20→32, seek-to-primary 8→24, primary-to-
secondary 16→24, plus 24 below to match. The full player had visible
slack above the controls; this redistributes it.
Title (22pt parchment) → artist (14pt ash) → album (12pt ash). Album
is conditional — drops out if MediaItem.album is empty rather than
leaving a blank line. Tightened the gap to the seek bar (24→20) to
absorb the new line on small screens.
Mini player simplifies to track-info + prev/play/next. The
shuffle/repeat/queue cluster moves to the full player, where it has
the room to breathe.
Full player (NowPlayingScreen) now has:
- Real album art (FileImage when artUri is file://, ServerImage from
/api/albums/<id>/cover otherwise — same auth-aware loader as the
rest of the app, with errorBuilder so a failed fetch falls back to
a slate placeholder instead of a broken-image glyph).
- Title row with inline like + kebab.
- Full-width seek with start/end timestamps below.
- 36/72/36 prev/play/next.
- Secondary row: shuffle, repeat, queue.
Mini ↔ Full transition mechanics:
- Tap mini → push /now-playing with custom slide-up transition
(CustomTransitionPage, 280ms easeOutCubic).
- Vertical drag-up flick on mini (>200 px/s) → same push.
- System back / leading expand-more icon → Navigator.pop, which the
CustomTransitionPage replays as a slide-down (240ms easeInCubic).
- Drag-down on full player past 80px OR a >500 px/s downward flick
→ Navigator.pop. Buttons and the seek slider stay tappable since
Flutter's gesture arena gives priority to the more-specific child
recognizers.
- Mini player hides while /now-playing is the active route — the
full player IS the player UI in that state, no need to fight over
visual space.
The 401s on /api/albums/<id>/cover were the root cause of "only the
first tile is navigable" — failed images leaving slate placeholders
that combined with the deferToChild hit-test (fixed in d703fc2) to
silently swallow taps.
ServerImage:
- sessionTokenProvider is a FutureProvider; .value is null after a
hot restart until secure-storage resolves. Old code fired
Image.network with headers:null at that moment, the network image
cache locked in the 401 response, and never retried. Switch to
AsyncValue.when so the widget waits for the token before mounting
Image.network with the auth header attached.
- Add errorBuilder so a single failed image renders the parent
fallback instead of leaking a stack trace + broken-icon glyph.
Player bar:
- media.artUri is set by AlbumCoverCache as Uri.file(path). Wrapping
it in NetworkImage attempts HTTP on a file:// URI and fails. Use
FileImage when the scheme is file, else NetworkImage.
Net effect: failed image loads no longer leak errors or block other
widgets from rendering / receiving taps.
Three issues from the screenshot:
1. Title invisible: LikeButton + TrackActionsButton were raw IconButtons
with the default 48dp tap target, eating ~96dp of the title row.
Wrap both in 32×32 SizedBox at the call site so the title actually
gets enough room to render (still ellipsizes if needed).
2. Layout per operator's revised spec: track info gets a 2:1 share of
the row vs the controls column. The controls column now stacks the
shuffle/repeat/queue sub-row above the prev/play/next sub-row, both
right-aligned.
3. Right-edge 2px overflow: previous play controls were 40+48+40=128dp
in a flex-1 slot of ~110dp. Resize to 32+40+32=104dp matching the
shuffle/repeat/queue row above (3×32=96dp), with the play button
slightly larger to keep visual hierarchy.
Drop the volume provider import since the slider is gone (handled by
phone hardware buttons).
Player bar: drop the volume slider — phone hardware controls volume.
Right cluster collapses to a single row of shuffle/repeat/queue.
Playlist card: GestureDetector defers to children by default, so taps
over the cover image area didn't always register. Add HitTestBehavior.opaque
so the whole card surface is tappable.
Update banner: was 3-4× the height of its text — IconButton's default
48dp tap target plus generous vertical padding dominated. Tighten
padding (8→4), shrink dismiss button to 32×32 with iconSize 16, slim
the action button to 28dp height with shrinkWrap tap target.
Home screen: ClampingScrollPhysics + 140dp bottom padding (already
applied in working tree) so scroll stops just above the mini-player.
