From 1f0f7eee1adf4cd4572bf7340620f0a9f98225dd Mon Sep 17 00:00:00 2001 From: Bryan Van Deusen Date: Tue, 12 May 2026 09:50:01 -0400 Subject: [PATCH 01/45] fix(playlists): unblock Discover by removing SELECT DISTINCT + ORDER BY plan error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The cross-user bucket query combined SELECT DISTINCT with ORDER BY md5(...), which Postgres rejects at plan time (SQLSTATE 42P10). buildDiscoverCandidates returned that error on first bucket failure, so the whole Discover playlist was skipped every nightly run — even though the random bucket pool was healthy. Switched to GROUP BY so the md5 ordering expression no longer needs to appear in the select list, and hardened the function so future single- bucket failures degrade gracefully via slot redistribution instead of taking out the whole playlist.

Mirrors the existing test-utils/mocks/likes.ts and test-utils/mocks/quarantine.ts convention. Tests with intentionally divergent shapes (AddToPlaylistMenu's richer createPlaylist payload, PlaylistCard's getPlaylist, route-specific mocks, events.svelte's specific resolved value) stay inline.

Added an Icons.restore IconButton on each tile that calls myQuarantineProvider.notifier.unflag(trackId) (the optimistic remove-with-rollback already lived on the notifier). - No album cover art — added a 56px ServerImage thumb matching the web page's 14×14 thumb, with the same fs.slate fallback compact_track_card uses for missing covers. - No relative timestamp — appended _relativeTime(row.createdAt) next to the reason pill so the user can tell "I hid this 3d ago" at a glance. Also collapsed the duplicate provider: _HiddenTab was watching a local FutureProvider that didn't see flag/unflag mutations, while the kebab's HideTrackSheet flow goes through the canonical myQuarantineProvider (AsyncNotifier). Switched _HiddenTab to watch myQuarantineProvider so flag-from-anywhere and unhide-from-the-tab stay in sync. The local _quarantineProvider was deleted; one source of truth now. Caught during the #375 DRY audit cross-check against the #356 inventory.

Ships the in-process pub/sub bus and the SSE subscriber endpoint; no producers wired yet, so the stream emits only heartbeats today. Verifiable in isolation by curl-ing the endpoint with a valid Bearer token — the connection opens, ": heartbeat" lines arrive every 15s, the connection closes cleanly on client disconnect. eventbus.Bus is a small fan-out broadcaster: subscribers register through Subscribe (returns a receive channel + an unsubscribe closure), writers call Publish, and the bus drops events for any subscriber whose buffer is full rather than blocking the writer. No persistence — clients are expected to resync via normal /api/* fetches on (re)connect. The SSE handler emits an initial ": connected" comment so the client sees the connection open immediately, then forwards events whose UserID matches the authenticated user (or is empty for broadcast). Heartbeat comments keep proxy connections alive. Context cancellation cleanly tears down the subscription on client disconnect. Producers (likes, request status, quarantine, scanner, playlist mutations) land in subsequent slices.

After this commit, an SSE subscriber sees real events fire: - track.liked / track.unliked when the user toggles the heart on a track (handleLikeTrack / handleUnlikeTrack). Album + artist like events intentionally deferred — they're symmetric trivial follow-ups but the operator's primary like surface is tracks. - request.status_changed when a Lidarr request is created, cancelled, approved, or rejected. Auto-approve will fire twice (pending then approved) in rapid succession, which is semantically correct; client invalidation handles that fine. Events are user-scoped via row.UserID so admin approve/reject route to the requester, not the admin acting. Helpers live in events_publish.go so the wire shape (kind names, payload keys) stays in one place — future producers in slice 3 reuse the same pattern. events_publish.go is no-op when h.eventbus is nil so tests that construct handlers without a bus continue to pass.

When the reconciler matches an approved Lidarr request against the library and flips it to 'completed', it now publishes a request.status_changed event scoped to the original requester so their /requests page invalidates without polling. Three call sites — one per kind (artist / album / track) — capture the completed row instead of discarding it so the publish has the user_id. Bus plumbing: the reconciler runs in cmd/minstrel/main.go which constructs services before server.New is called. Moved bus construction into main; the Server struct gained a Bus field that Router() reads, falling back to a fresh local instance when nil (test contexts). Result: one bus per process shared by every publisher and the SSE subscriber endpoint. reconciler.go inlines a uuid->string helper rather than reaching into internal/api for one — avoids a back-edge dependency. Test compat: 9 NewReconciler call sites in reconciler_integration_test.go get `nil` for the new bus param. The reconciler's publishCompleted helper is a no-op when the bus is nil so tests that don't care about events keep passing. Scanner producer (scan.progress) deferred to slice 3c — needs more thought about which lifecycle transitions warrant events vs. flood the stream.

Publishes scan.run_started when InsertScanRun succeeds and scan.run_finished after FinishScanRun completes (success or with an error_message payload). Per-file progress events are intentionally NOT emitted — they'd flood the stream during large library scans without giving the admin scan card anything actionable. The two-beat signal gives the UI enough to invalidate scanStatusProvider at the right moments. Bus access uses a package-level setter on internal/library because threading bus through RunScan + TryStartScan + Scheduler + all their callers would touch ~10 sites without changing behavior at the boundaries that don't publish. Per-process singleton, matches the log.SetDefault idiom. cmd/minstrel/main.go calls library.SetEventBus(bus) once at startup; test contexts that never call it skip publishing safely (publishScanEvent is a no-op when bus is nil). This completes the server side of #392. Slice 4 wires the Flutter consumer: live_events_provider.dart (StreamProvider) + live_events_dispatcher.dart (event-kind → provider invalidation) + AppLifecycleState cold-start invalidation.

Heartbeat comments are silently dropped; malformed JSON frames are skipped. The provider auto-rebuilds when auth state changes (token rotation, sign-out → sign-in), so reconnect is implicit. live_events_dispatcher.dart listens to the stream and invalidates the small set of publicly-importable providers we know about: - myQuarantineProvider + homeProvider on any quarantine.* event - homeProvider on any playlist.* event (Home renders the Playlists row) Screen-private providers (library_screen.dart's _liked* / _libraryAlbums / _history, admin screens, etc.) opt in to live-refresh by themselves listening to liveEventsProvider in follow-up commits; the dispatcher stays small and avoids back-edge dependencies on every feature folder. The dispatcher also installs an AppLifecycleState observer for resume-time defensive invalidation. SSE will catch up on its own when the app returns from background, but the invalidate flushes any stale data immediately so the first frame back is fresh. app.dart wires the dispatcher into the post-first-frame callback alongside the other startup activations.

For-You seed rotates daily across the user's top-5 most-played tracks. pickForYouSeedForDay uses userIDHash(user, day) mod len(seeds) so today's mix uses an entirely different similarity pool than tomorrow's. Within-day determinism preserved. 2. JitterMagnitude bumped 0.0 → 0.1. The scoring RNG is now seeded by userIDHash(user, day) rather than the no-op, so near-tied candidates shuffle daily without breaking within-day stability. 3. Head/tail split moves from 20+5 to 12+13. Roughly half the playlist comes from the tail now (daily-deterministic via tieBreakHash), giving the user substantially different content while a 12-track anchor of strong similarity matches keeps the mix recognizable. 4. Songs-Like-X seed artists shuffle daily across the user's top-5 played artists. pickSeedArtistsForDay applies a userIDHash-seeded Fisher-Yates and takes 3. 5. scoreAndSortCandidates / pickTopN / pickHeadAndTail gain a userID parameter so the RNG can be seeded per-user; existing call sites updated; noopRNG removed. Test fixtures widened similarity gaps (e.g. float64(50-i) instead of (50-i)/50) so the new jitter (±0.1) doesn't perturb head ordering in assertions about the head/tail mechanism. New seed_selection_test coverage for userIDHash + pickForYouSeedForDay + pickSeedArtistsForDay spans deterministic-within-day, varies-across-days, and graceful degradation with small candidate pools. PickTopPlayedTrackForUser replaced by PickTopPlayedTracksForUser :many in the prior commit (b4801c2). The For-You seed lookup now goes through pickForYouSeedForDay over the returned slice. PickSeedArtists's LIMIT widened to 5 in the same prior commit. For #392 Half A — system playlist content diversity. Half B (per-user timezone scheduling) is a separate spec.

Uses github.com/go-co-op/gocron/v2 with WithLocation(userTZ) for each user's job. Hourly reconciliation pass keeps the in-memory job set in sync with the active-users query. Start sequence: clear stale in_flight rows; register a daily job for every active user at their stored timezone; fire a one-shot runOnce to catch up missed schedules during downtime; start gocron. Stop drains and shuts down the gocron loop. Refresh(ctx, userID) removes the user's existing job (if any) and registers a fresh one at their current timezone — wired into the PUT /api/me/timezone handler and new-user registration in the next commit. Server struct gains PlaylistScheduler; main.go constructs it after the eventbus and threads it through to api.Mount. The existing StartSystemPlaylistCron call stays for one more commit so we don't have a window where no scheduler is running; Task 3 deletes it.

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. For #396 / #356 umbrella.

Closes the inconsistency caught during the #375 DRY audit (the queue row had a "you are here" indicator; other track-row surfaces did not). Web — TrackRow.svelte + PlaylistTrackRow.svelte: isCurrent = player.current?.id === track.id → border-l-2 border-l-accent bg-surface-hover when true. PlaylistTrackRow additionally gates on !isUnavailable so deleted rows never match a phantom playing id. Flutter — TrackRow + _PlaylistTrackRow: TrackRow becomes a ConsumerWidget, watches mediaItemProvider, and wraps its InkWell in a Container whose BoxDecoration carries the fs.iron background + 2px fs.accent left border when current. Title text also shifts to fs.accent and FontWeight.w500. Same pattern for _PlaylistTrackRow. No "Now playing" pill on these surfaces — the player bar already names the track, so the accent band alone reads as enough cue. For #401 / #356 umbrella.

Closes that gap so the Flutter Liked tab's albums and artists sub-lists can listen for changes the same way the tracks sub-list will (#402 wire-up lands next commit). publishLikeEvent already handles the entity_type dispatch; the four handler call sites just need the new lines.

Screen-scoped providers (file-private in their feature folders) get their own ref.listen(liveEventsProvider, ...) so they go live without needing back-edge dependencies from /shared. Five screens wired: - library_screen.dart _LikedTab — invalidates _likedTracksProvider / _likedAlbumsProvider / _likedArtistsProvider on any of the six track/album/artist like/unlike kinds. - playlist_detail_screen.dart — invalidates playlistDetailProvider(id) on playlist.updated / playlist.tracks_changed matching the visible playlist_id. On playlist.deleted matching the visible id, pops back so the user isn't left staring at a gone playlist. - admin_requests_screen.dart — invalidates adminRequestsProvider on request.status_changed (covers user create/cancel + admin approve/reject + reconciler complete). - admin_quarantine_screen.dart — invalidates adminQuarantineProvider on any quarantine.* event (flag from a user / admin resolve / file delete / lidarr delete). - requests_screen.dart (own requests) — invalidates myRequestsProvider on request.status_changed. Server-side events are user-scoped via publishRequestStatusChanged's row.UserID, so admin actions on someone else's request route to the right stream. History tab is NOT wired (no server-side play.scrobbled event yet — documented in #402 body as deferred until that event ships).

Only updated the 6 files that failed; 16 other player-store mocks exist across the suite but their tests don't render Track/Playlist rows so the derivation never fires.

This commit caches the last successful HomeData as a single-row JSON blob in drift, so subsequent app opens yield content immediately and revalidate in the background. Schema: - New CachedHomeSnapshot table (single row: id=1, json TEXT, updated_at). schemaVersion bumped 2 → 3 with a forward migration that calls m.createTable(cachedHomeSnapshot). Codegen regenerated via build_runner; the *.g.dart files are gitignored and rebuilt by the CI Codegen step. Provider rewrite: - homeProvider: FutureProvider → StreamProvider using the existing cacheFirst pattern (alwaysRefresh: true for SWR). On cold cache the first /api/home fetch populates the row. On warm cache the cached HomeData is yielded immediately and a background REST fetch overwrites the row, which drift's watch() picks up. - Encoder helpers (_albumToJson / _artistToJson / _trackToJson) so HomeData survives the JSON round-trip into and out of drift. Field names match the server's /api/home wire shape exactly so HomeData.fromJson handles both fresh server responses and cached drift rows. Callers untouched: home_screen.dart's ref.watch + ref.refresh + metadata_prefetcher's ref.listen all keep working with the StreamProvider shape (AsyncValue stays the surface type). Test fix: 4 homeProvider.overrideWith sites in home_screen_test.dart switched from `(ref) async => _emptyHome` (FutureProvider form) to `(ref) => Stream.value(_emptyHome)` (StreamProvider form). For #357. Completes the user-visible deferred follow-up. Remaining deferred items: library_changes server-side retention.

The library_changes table is the append-only change log that drives /api/library/sync's delta semantics — every mutation (scanner upsert, like, playlist edit, track delete) writes one row. Without a retention policy the table grows unbounded; the original migration (0025) called out the follow-up explicitly. New goroutine: sync.Compactor runs daily, deletes rows where changed_at < now - 30 days. Logs a row count when non-zero so operators can see compaction activity in the journal. First tick fires on startup so a process that hasn't been compacted in a while catches up immediately. 30-day retention matches the offline-mode spec (docs/superpowers/specs/2026-05-09-flutter-offline-mode-design.md). Clients with a cursor older than that hit the existing 410 fallback path and resync from scratch. Imported as syncpkg in main.go to follow the existing convention (see internal/library/scanner.go).

The /healthz server handler itself is fine (microsecond JSON encode); the blocker was client-side. Three issues fixed in one pass: 1. Optimistic render. VersionGate becomes a ConsumerStatefulWidget that always renders its child and just activates the version check controller on mount. The "you're too old" experience moves from a full-screen hard-block (_TooOldScreen, deleted) to a soft banner above the AppBar that lets the user keep playing cached content while they update. 2. 1h-throttled background check. New VersionCheckController (AsyncNotifier) hydrates from a secure-storage cache on boot, returning the cached result instantly. If the cache is missing or >1h old, fires a background recheck. AppLifecycleState.resumed triggers recheckIfStale so foregrounding after >1h re-checks without per-frame hammering. "Check now" button on the banner bypasses the staleness gate so dev iteration (push new APK, want to see banner clear) doesn't wait an hour. 3. Bounded health-check dio. The /healthz request uses a dedicated dio with connectTimeout: 3s + receiveTimeout: 2s rather than the default 8s / 30s. Health probes should fail fast — if the server can't ack in 5s, the user has bigger problems than a stale min_client_version and the cached value remains in effect. Cache keys live alongside the existing tz cadence cache in flutter_secure_storage (kResult + kAtMs). On any network error or parse failure, _runCheck soft-fails without bumping the timestamp, so the next staleness check will retry. VersionTooOldBanner renders in _ShellWithPlayerBar's Column above the existing UpdateBanner — the two coexist when both apply (server rejects you AND an APK is queued).

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. --- .../lib/discover/discover_screen.dart | 12 ++++-- flutter_client/lib/player/player_bar.dart | 8 +++- .../lib/shared/widgets/server_image.dart | 40 ++++++++++++------- flutter_client/pubspec.lock | 32 +++++++++++++++ flutter_client/pubspec.yaml | 7 ++++ 5 files changed, 81 insertions(+), 18 deletions(-) diff --git a/flutter_client/lib/discover/discover_screen.dart b/flutter_client/lib/discover/discover_screen.dart index 409347be..92b6151d 100644 --- a/flutter_client/lib/discover/discover_screen.dart +++ b/flutter_client/lib/discover/discover_screen.dart @@ -1,3 +1,4 @@ +import 'package:cached_network_image/cached_network_image.dart'; import 'package:dio/dio.dart'; import 'package:flutter/material.dart'; import 'package:flutter_riverpod/flutter_riverpod.dart'; @@ -204,9 +205,14 @@ class _ResultTile extends StatelessWidget { color: fs.slate, child: row.imageUrl.isEmpty ?

See docs/superpowers/specs/2026-05-13-per-item-rendering-design.md for the full architecture rationale. --- flutter_client/lib/cache/db.dart | 31 ++- flutter_client/lib/cache/hydration_queue.dart | 137 ++++++++++++ flutter_client/lib/cache/tile_providers.dart | 124 +++++++++++ .../lib/shared/widgets/skeletons.dart | 199 ++++++++++++++++++ 4 files changed, 490 insertions(+), 1 deletion(-) create mode 100644 flutter_client/lib/cache/hydration_queue.dart create mode 100644 flutter_client/lib/cache/tile_providers.dart create mode 100644 flutter_client/lib/shared/widgets/skeletons.dart diff --git a/flutter_client/lib/cache/db.dart b/flutter_client/lib/cache/db.dart index f5ef32b8..d2227677 100644 --- a/flutter_client/lib/cache/db.dart +++ b/flutter_client/lib/cache/db.dart @@ -142,6 +142,27 @@ class CachedHistorySnapshot extends Table { Set get primaryKey => {id}; } +/// Section→position→entity-id index for the home screen, populated +/// from the per-item discovery endpoint `/api/home/index`.

Home now reads from the new homeIndexProvider (drift-first over CachedHomeIndex with /api/home/index discovery + SWR), then each tile is a small ConsumerWidget watching its own albumTileProvider/artistTileProvider/ trackTileProvider. Tiles render a matched-dimension skeleton while their entity is still hydrating, and swap in the real card once drift emits the populated row. Track hydration is wired up — /api/tracks/:id already existed so the queue's case 'track' just calls api.getTrack(id) and persists. The visible behavior: * Cold visit: small /api/home/index round-trip (IDs only, ~10× smaller than /api/home), then sections appear shaped with skeleton tiles; each tile materializes as the hydration queue drains. No more "30s blank → everything pops in at once." * Warm visit: drift index emits instantly, drift entity rows emit instantly, no network. Page paints fully in the first frame. * Mid-state: scrolling through a partially-hydrated section sees real cards next to skeleton cards. Layout doesn't shift because skeletons match real-card dimensions exactly. CachedHomeSnapshot (and the legacy homeProvider) stay in place but unconsumed by Flutter — left in for now so revert is cheap if the new path needs reworking. Cleanup follow-up in a later slice. Old /api/home endpoint untouched, so the web client keeps working unchanged. --- flutter_client/lib/api/endpoints/library.dart | 19 ++ flutter_client/lib/cache/hydration_queue.dart | 12 +- flutter_client/lib/cache/tile_providers.dart | 14 +- flutter_client/lib/library/home_screen.dart | 263 +++++++++++------- .../lib/library/library_providers.dart | 90 ++++++ flutter_client/lib/models/home_index.dart | 41 +++ .../test/library/home_screen_test.dart | 62 ++--- 7 files changed, 345 insertions(+), 156 deletions(-) create mode 100644 flutter_client/lib/models/home_index.dart diff --git a/flutter_client/lib/api/endpoints/library.dart b/flutter_client/lib/api/endpoints/library.dart index 8fab0c23..6d38b154 100644 --- a/flutter_client/lib/api/endpoints/library.dart +++ b/flutter_client/lib/api/endpoints/library.dart @@ -3,6 +3,7 @@ import 'package:dio/dio.dart'; import '../../models/album.dart'; import '../../models/artist.dart'; import '../../models/home_data.dart'; +import '../../models/home_index.dart'; import '../../models/track.dart'; /// LibraryApi wraps the server's native /api/* library surface. @@ -27,6 +28,24 @@ class LibraryApi { return HomeData.fromJson(r.data ?? const {}); } + /// GET /api/home/index — per-item rendering variant.

Now it renders the header + seed.trackCount worth of skeleton rows (capped at 8 when no seed is present). The real list swaps in without a layout jump. Slice D was originally scoped for per-track hydration through a new discovery endpoint, but the unavailable-entries data model (playlist rows that lost their underlying track to deletion / quarantine) make that disproportionately expensive — would require a schema change to support null trackIds on cached_playlist_tracks, a server endpoint, and a screen rewrite. The skeleton-row approach captures ~80% of the perceptual win at a fraction of the cost. True per-track hydration remains a future opportunity if cold visits to very large playlists still feel sluggish after Slice F polish lands. --- .../lib/playlists/playlist_detail_screen.dart | 109 ++++++++++++------ 1 file changed, 76 insertions(+), 33 deletions(-) diff --git a/flutter_client/lib/playlists/playlist_detail_screen.dart b/flutter_client/lib/playlists/playlist_detail_screen.dart index 1e0b0fbb..9b4262a7 100644 --- a/flutter_client/lib/playlists/playlist_detail_screen.dart +++ b/flutter_client/lib/playlists/playlist_detail_screen.dart @@ -68,12 +68,12 @@ class PlaylistDetailScreen extends ConsumerWidget { ), ), body: detail.when( - // Loading from a seed: render the header immediately + a - // small inline "loading tracks" hint, instead of an opaque - // full-screen spinner.

Wraps every tile widget in an AnimatedSwitcher between the skeleton placeholder and the real card. 220ms cross-fade with easeOut: tiles "settle into place" rather than hard-cutting from shimmer to content. Since each tile fades independently as its data lands — and the HydrationQueue's concurrency cap drains in a natural cascade — the overall feel is the staged "page builds piece by piece" effect we wanted, with no per-tile position math required. Bumps CachedNetworkImage fadeInDuration from zero to 120ms (server_ image.dart, discover_screen.dart). Imperceptible on cache hits since the image decodes synchronously; on cache misses the bytes fade in smoothly instead of popping. Slice 1's "zero fade" call was right about the 500ms default being a regression, but 120ms threads the needle. Playlist detail wraps its body in the same AnimatedSwitcher so the cold-load skeleton page cross-fades into the real track list. Tiles affected: home _AlbumTile / _ArtistTile / _TrackTile + liked _LikedAlbumTile / _LikedArtistTile / _LikedTrackRow + playlist _SkeletonBody / _Body. All keyed via ValueKey so AnimatedSwitcher detects the transition. End of the per-item pass. Net behavior: cold visits paint shaped pages instantly with skeletons, content cascades in as hydration lands; warm visits paint fully from drift in the first frame. --- .../lib/discover/discover_screen.dart | 2 +- flutter_client/lib/library/home_screen.dart | 60 +++++++++++----- .../lib/library/library_screen.dart | 70 +++++++++++++------ .../lib/playlists/playlist_detail_screen.dart | 31 ++++---- .../lib/shared/widgets/server_image.dart | 10 +-- 5 files changed, 115 insertions(+), 58 deletions(-) diff --git a/flutter_client/lib/discover/discover_screen.dart b/flutter_client/lib/discover/discover_screen.dart index 92b6151d..ff1ea8a2 100644 --- a/flutter_client/lib/discover/discover_screen.dart +++ b/flutter_client/lib/discover/discover_screen.dart @@ -208,7 +208,7 @@ class _ResultTile extends StatelessWidget { : CachedNetworkImage( imageUrl: row.imageUrl, fit: BoxFit.cover, - fadeInDuration: Duration.zero, + fadeInDuration: const Duration(milliseconds: 120), fadeOutDuration: Duration.zero, errorWidget: (_, __, ___) => Icon(Icons.album, color: fs.ash), diff --git a/flutter_client/lib/library/home_screen.dart b/flutter_client/lib/library/home_screen.dart index c8f01a74..968ed772 100644 --- a/flutter_client/lib/library/home_screen.dart +++ b/flutter_client/lib/library/home_screen.dart @@ -83,6 +83,13 @@ class HomeScreen extends ConsumerWidget { // ─── Per-tile widgets ──────────────────────────────────────────────── +/// Duration of the skeleton→content cross-fade. 220ms reads as "tile +/// settled into place" — longer drags, shorter feels like a hard cut. +/// Each tile cross-fades independently when its data lands, so the +/// natural cascade from the hydration queue's bounded concurrency +/// produces a staged-reveal feel without any per-tile delay math. +const Duration _tileRevealDuration = Duration(milliseconds: 220); + /// Album tile: skeleton until albumTileProvider yields a populated row. class _AlbumTile extends ConsumerWidget { const _AlbumTile({required this.id}); @@ -92,10 +99,17 @@ class _AlbumTile extends ConsumerWidget { Widget build(BuildContext context, WidgetRef ref) { final asyncAlbum = ref.watch(albumTileProvider(id)); final album = asyncAlbum.asData?.value; - if (album == null) return const SkeletonAlbumTile(); - return AlbumCard( - album: album, - onTap: () => context.push('/albums/${album.id}', extra: album), + return AnimatedSwitcher( + duration: _tileRevealDuration, + switchInCurve: Curves.easeOut, + child: album == null + ?
