**Duration:** 7 min - **Started:** 2026-03-15T18:52:57Z - **Completed:** 2026-03-15T18:59:57Z - **Tasks:** 2 - **Files modified:** 17 ## Accomplishments - Flutter project scaffolded with all runtime and dev dependencies resolved - Drift AppDatabase with schemaVersion 1 and make-migrations workflow capturing drift_schema_v1.json - Riverpod providers generated via @riverpod annotation (database_provider, theme_provider) - Light and dark themes with sage green seed (0xFF7A9A6D) and warm stone/charcoal surface overrides - ThemeNotifier defaults to ThemeMode.system with SharedPreferences persistence - Full German ARB localization with 15 keys covering all Phase 1 screens (proper umlauts) - 14 Wave 0 tests all passing: database (3), color scheme (6), theme switching (3), localization (2) ## Task Commits Each task was committed atomically: 1. **Task 1: Create Flutter project and configure all dependencies and tooling** - `4b27aea` (chore) 2. **Task 2: Create core infrastructure, localization strings, and Wave 0 test scaffolding** - `51738f7` (feat) ## Files Created/Modified - `pubspec.yaml` - All dependencies (flutter_riverpod, drift, go_router, etc.) - `analysis_options.yaml` - riverpod_lint plugin configuration - `build.yaml` - Drift code generation configuration - `l10n.yaml` - ARB localization configuration (German template) - `lib/core/database/database.dart` - AppDatabase class with schemaVersion 1 - `lib/core/database/database.g.dart` - Generated Drift database code - `lib/core/providers/database_provider.dart` - Riverpod provider for AppDatabase - `lib/core/providers/database_provider.g.dart` - Generated provider code - `lib/core/theme/app_theme.dart` - Light and dark ThemeData with sage & stone palette - `lib/core/theme/theme_provider.dart` - ThemeNotifier with SharedPreferences persistence -

`test/l10n/localization_test.dart` - Localization widget tests (FOUND-03) ## Decisions Made - **drift/drift_dev pinned to 2.31.0:** drift_dev 2.32.0 requires analyzer ^10.0.0 which is incompatible with riverpod_generator 4.0.3's analyzer ^9.0.0. Downgrading to 2.31.0 (analyzer >=8.1.0 <11.0.0) resolves the conflict with no functional difference for Phase 1. - **Riverpod 3 provider naming:** Generated provider is `themeProvider` (not `themeNotifierProvider`) per Riverpod 3 naming convention where the Notifier suffix is dropped. ## Deviations from Plan ### Auto-fixed Issues **1. [Rule 3 - Blocking] Resolved analyzer version conflict between drift_dev and riverpod_generator** - **Found during:** Task 1 (dependency installation) - **Issue:** drift_dev 2.32.0 requires analyzer ^10.0.0, riverpod_generator 4.0.3 requires analyzer ^9.0.0 -- mutually exclusive - **Fix:** Pinned drift to 2.31.0 and drift_dev to 2.31.0 (analyzer >=8.1.0 <11.0.0, compatible with ^9.0.0) - **Files modified:** pubspec.yaml - **Verification:** flutter pub get succeeds, all code generation works - **Committed in:** 4b27aea (Task 1 commit) **2. [Rule 3 - Blocking] Created l10n directory and minimal ARB file for flutter pub get** - **Found during:** Task 1 (dependency verification) - **Issue:** l10n.yaml references lib/l10n/app_de.arb which doesn't exist yet, causing flutter pub get to fail - **Fix:** Created lib/l10n/ directory with minimal ARB file (expanded in Task 2) - **Files modified:** lib/l10n/app_de.arb - **Verification:** flutter pub get succeeds without localization errors - **Committed in:** 4b27aea (Task 1 commit) **3. [Rule 1 - Bug] Fixed provider name in theme tests** - **Found during:** Task 2 (test creation) - **Issue:** Test used `themeNotifierProvider` but Riverpod 3 generates `themeProvider` - **Fix:** Updated all test references from `themeNotifierProvider` to `themeProvider` - **Files modified:** test/core/theme/theme_test.dart - **Verification:** dart analyze clean, flutter test passes - **Committed in:** 51738f7 (Task 2 commit) --- **Total deviations:** 3 auto-fixed (1 bug, 2 blocking) **Impact on plan:** All auto-fixes necessary for dependency resolution and test correctness. No scope creep. ## Issues Encountered - Default widget_test.dart referenced removed MyApp class -- deleted as part of Task 2 - Generated database.g.dart has unused field warning (_db) -- this is in auto-generated code and cannot be fixed ## User Setup Required None - no external service configuration required. ## Next Phase Readiness - All core infrastructure ready for Plan 02 (navigation shell, placeholder screens, settings, full app wiring) - Drift database ready to receive tables in Phase 2 - Riverpod code generation pipeline established - Theme and localization ready for UI consumption - riverpod_lint active (warnings appear in dart analyze output) ## Self-Check: PASSED - All 20 key files verified present on disk - Both task commits verified in git log (4b27aea, 51738f7) - 14/14 tests passing (flutter test) - dart analyze: 0 errors (2 warnings in generated code only) --- *Phase: 01-foundation* *Completed: 2026-03-15*
