# Phase 1 Plan 01: Project Scaffold Summary

**Drift database (schema v1) with migration workflow, Riverpod 3 providers with code generation, sage & stone Material 3 theme, and German ARB localization -- 14 Wave 0 tests passing**

## Performance

- **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
- `lib/core/theme/theme_provider.g.dart` - Generated theme provider code
- `lib/l10n/app_de.arb` - German localization strings (15 keys)
- `lib/l10n/app_localizations.dart` - Generated localization delegate
- `lib/l10n/app_localizations_de.dart` - Generated German localization implementation
- `lib/main.dart` - Minimal ProviderScope placeholder
- `drift_schemas/household_keeper/drift_schema_v1.json` - Schema v1 migration capture
- `test/core/database/database_test.dart` - Database unit tests (FOUND-01)
- `test/core/theme/color_scheme_test.dart` - ColorScheme unit tests (THEME-02)
- `test/core/theme/theme_test.dart` - Theme switching tests (THEME-01)
- `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)
