All six tests had been silently skipped under @Tags(['drift']) for 6+ months, so they accumulated test-vs-implementation drift. Now running against the libsqlite3-bearing ci-flutter:3.44 image, each failed for a distinct reason. Diagnoses below. audio_cache_manager_test 'usageBytes sums sizeBytes across rows': usageBytes() is a directory walk (authoritative on-disk total, catches orphan partials the index misses). The test inserted drift rows but never wrote files, so the walk returned 0. The actual API for summing drift sizeBytes is bucketUsage(). Rename to 'bucketUsage sums drift sizeBytes across rows', use that API, assert liked+rolling == 350. Also give the two rows unique paths per row-shape sanity. sync_controller_test (3 200-path tests, all returning null result): Map literals in Dart 3 with mixed value types infer as Map<String, Object>, not Map<String, dynamic>. The sync controller casts `resp.data as Map<String, dynamic>` (and several nested casts), which is invariant on generics and throws TypeError. The silent try/catch in sync() swallowed the throw and returned null. Real JSON parsing produces Map<String, dynamic>, so this never surfaced in production. Fix: route the test stub body through jsonDecode(jsonEncode(body)) in _stubDio — mimics real Dio's parsed-response shape. Affects '200 with artist upsert', '200 with track delete', and 'like_track upsert + delete round-trip'. quarantine_provider_test 'flag keeps drift optimistic + queues mutation on server failure': When the API stub throws, the controller catches + queues to CachedMutations. The drift watch() stream in MyQuarantineController was still in loading state when addTearDown disposed the container, tripping Riverpod's "StreamProvider disposed during loading" assertion. The success-path tests resolved before tearDown so they didn't see it. Fix: await one microtask before the test ends so the stream emits. like_button_test 'tap toggles icon optimistically; rollback on error': After the LikeButton was migrated to LucideHeart in the Lucide sweep, the prior fix replaced the find.byIcon assertion with a heartFilled() helper reading LucideHeart.filled. But likesController .toggle() goes through an async chain (optimistic state flip + await api.like + state notification), which one frame of tester.pump() doesn't flush. Use pumpAndSettle after both tap and rollback toggle so the widget rebuilds with the new state before the assertion. After this push, the drift cohort should be all-green on the libsqlite3-bearing image. Fable #399 / local #62. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Minstrel mobile client
Flutter (iOS + Android) sibling of the SvelteKit web SPA. v1 first slice ships: scaffold, auth, library browse (home / artist / album), likes, player with background audio + lock-screen controls.
Setup
cd flutter_client
flutter pub get
./tool/sync_shared.sh # copy tokens / error-copy / placeholders from ../web
dart run tool/gen_tokens.dart # regen lib/theme/tokens.dart from shared/fabledsword.tokens.json
flutter run
sync_shared.sh is idempotent. CI runs it on every build; rerun locally
whenever web/src/lib/styles/tokens.json,
web/src/lib/styles/error-copy.json, or
web/static/placeholders/album-fallback.svg changes.
Project layout
See docs/superpowers/specs/2026-05-02-flutter-mobile-foundation-design.md
section 3. Briefly:
lib/api/— dio client, ApiError, error-copy loader, per-surface endpoints.lib/auth/— server URL screen, login screen, AuthController + secure storage.lib/library/— home, artist detail, album detail, providers, widgets.lib/likes/— LikeButton + optimistic toggle controller.lib/player/— audio handler, player provider, mini PlayerBar, NowPlaying.lib/theme/— FabledSword token Dart class (generated), ThemeExtension, ThemeData.lib/shared/— routing (go_router shell), version gate, connection error banner.
shared/fabledsword.tokens.json and assets/error-copy.json are
synced from web/. Don't edit them directly — edit web/src/lib/styles/
and re-run ./tool/sync_shared.sh.
Architecture
- State: Riverpod 2 (
AsyncValue,AsyncNotifier, family providers). - HTTP: dio 5 with a Bearer-auth interceptor; 401 clears the session and the router redirects to login.
- Audio: just_audio wrapped by audio_service for background playback + lock-screen / notification controls.
- Auth: Bearer tokens in flutter_secure_storage. Server already
supports both cookie (web SPA) and Bearer (
internal/auth/session.go). - Routing: go_router with a ShellRoute so the PlayerBar persists
across navigation. Cold launch flow: no server-url →
/server-url, url set / no token →/login, token present →/home.
CI
.forgejo/workflows/flutter.yml runs on push to dev/main, tag pushes,
PR to main, and manual dispatch — path-filtered to flutter_client/**
plus the shared web inputs. Steps: sync, analyze, test, build APK.
Debug APKs upload as artifacts; release APKs attach to the Forgejo
release on tag.
Versioning
pubspec.yaml version mirrors the server tag (e.g. server v0.1.0
→ Flutter 0.1.0+1). The server's /healthz returns
min_client_version; old clients show an Update Required modal and
refuse to operate. Bump internal/server/version.go MinClientVersion
when a server-side change requires a paired client update.
Distribution
- Android: APK on the Forgejo release page. No Play Store for v1.
- iOS: TestFlight on tag (manual upload v1, automate later).
Out-of-scope for slice 1
Search, discover, requests, settings beyond server URL, admin, listening history, playlists, offline cache (#357). Those land in subsequent slices with their own brainstorm/spec/plan cycles. Per the operator's M7 ordering decision (2026-05-02), slice 2+ pauses to ship the missing web features first (#352 playlists, #362 theme toggle, #363 queue UI, #364 listening history, etc.) before mirroring on Flutter.
