# Phase 2 Plan 02: Room UI Summary
**2-column reorderable room card grid with Riverpod providers, room create/edit form with icon picker bottom sheet, delete confirmation dialog, and nested GoRouter routes**
## Performance
- **Duration:** 11 min
- **Started:** 2026-03-15T20:56:46Z
- **Completed:** 2026-03-15T21:08:00Z
- **Tasks:** 2
- **Files modified:** 14
## Accomplishments
- Riverpod providers connecting room UI to data layer with stream-based reactivity
- RoomsScreen with 2-column reorderable card grid, empty state, loading/error states, and FAB
- RoomCard displaying icon, name, due task count badge, and thin cleanliness progress bar with color interpolation
- RoomFormScreen handling both create and edit modes with name validation and icon picker
- IconPickerSheet with 25 curated Material Icons in a 5-column grid bottom sheet
- Nested GoRouter routes for room CRUD and placeholder task routes
- 11 new German localization keys with proper Unicode umlauts
## Task Commits
Each task was committed atomically:
1. **Task 1: Create Riverpod providers, room form screen, and icon picker** - `32e61e4` (feat)
2. **Task 2: Build rooms screen with reorderable card grid and room card** - `519a56b` (feat)
## Files Created/Modified
- `lib/features/rooms/presentation/room_providers.dart` - Riverpod providers (roomWithStatsList stream, RoomActions notifier)
- `lib/features/rooms/presentation/room_providers.g.dart` - Generated provider code
- `lib/features/rooms/presentation/room_card.dart` - Room card with icon, name, due count, cleanliness bar
- `lib/features/rooms/presentation/room_form_screen.dart` - Full-screen create/edit form with name field and icon picker
- `lib/features/rooms/presentation/icon_picker_sheet.dart` - Bottom sheet with curated Material Icons grid
- `lib/features/rooms/presentation/rooms_screen.dart` - Replaced placeholder with ConsumerWidget reorderable grid
- `lib/features/tasks/presentation/task_list_screen.dart` - Placeholder for Plan 03
- `lib/features/tasks/presentation/task_form_screen.dart` - Placeholder expanded by pre-commit hook
- `lib/core/router/router.dart` - Added nested routes: /rooms/new, /rooms/:roomId, /rooms/:roomId/edit, task routes
- `lib/l10n/app_de.arb` - 11 new room management keys with German umlauts
- `pubspec.yaml` - Added flutter_reorderable_grid_view dependency
- `test/shell/app_shell_test.dart` - Fixed with provider override for stream provider
## Decisions Made
- Used ReorderableBuilder<Widget> with typed onReorder callback for drag-and-drop grid reorder
- Implemented long-press context menu (bottom sheet) for edit/delete actions instead of popup menu for better mobile UX
- Added provider override pattern in app_shell_test to decouple navigation tests from database dependency
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 1 - Bug] Fixed app_shell_test pumpAndSettle timeout**
- **Found during:** Task 2 (rooms screen implementation)
- **Issue:** RoomsScreen now uses ConsumerWidget with stream provider, causing CircularProgressIndicator infinite animation in tests
- **Fix:** Added roomWithStatsListProvider.overrideWith returning Stream.value([]) in test ProviderScope
- **Files modified:** test/shell/app_shell_test.dart
- **Verification:** All 59 tests pass
- **Committed in:** 519a56b (Task 2 commit)
**2. [Rule 3 - Blocking] Generated missing task_providers.g.dart**
- **Found during:** Task 2 (verification)
- **Issue:** Pre-commit hook expanded task_form_screen.dart and task_providers.dart from Plan 01, but task_providers.g.dart was never generated due to a previous build_runner error
- **Fix:** Regenerated l10n and build_runner to produce task_providers.g.dart and new ARB keys
- **Files modified:** lib/features/tasks/presentation/task_providers.g.dart, lib/l10n/app_de.arb, lib/l10n/app_localizations.dart, lib/l10n/app_localizations_de.dart
- **Verification:** All 59 tests pass, dart analyze clean on room presentation files
- **Committed in:** 519a56b (Task 2 commit)
---
**Total deviations:** 2 auto-fixed (1 bug, 1 blocking)
**Impact on plan:** Both auto-fixes necessary for test correctness. No scope creep.
## Issues Encountered
- Pre-commit hook expanded placeholder task_form_screen.dart and task_providers.dart with full Plan 03 implementations, requiring additional l10n and build_runner regeneration to resolve compilation errors
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Room management UI complete and connected to data layer via Riverpod providers
- Task list and task form placeholder screens ready for Plan 03 implementation
- Nested GoRouter routes established for task CRUD navigation
- All 59 tests passing, dart analyze clean on room presentation files
## Self-Check: PASSED
All 13 key files verified present. Both task commits (32e61e4, 519a56b) verified in git log. 59 tests passing. dart analyze clean on room presentation files.
