SettingsScreen with Benachrichtigungen section (SwitchListTile + AnimatedSize time picker)
Permission flow
request on toggle ON, revert on denial with SnackBar hint
Notification scheduling with task/overdue counts from DailyPlanDao
Notification tap navigation via router.go('/') in NotificationService._onTap
Widget tests for notification settings UI states
end-to-end notification flow complete
added patterns
ConsumerStatefulWidget for screens requiring async callbacks with BuildContext
AnimatedSize for progressive disclosure of conditional UI sections
overrideWithValue for Riverpod provider isolation in widget tests

openNotificationSettings() not available in flutter_local_notifications v21 — simplified SnackBar to informational only (no action button)
ConsumerStatefulWidget chosen over ConsumerWidget for async callback isolation and mounted checks
notificationSettingsProvider (Riverpod 3 name, not notificationSettingsNotifierProvider) used throughout
ConsumerStatefulWidget pattern: async permission/scheduling callbacks use mounted guards after every await
TDD with pre-existing implementation: write tests to document expected behavior, verify pass, commit as feat (not separate test/feat commits)

Phase 4 Plan 2: Notification Settings UI Summary

ConsumerStatefulWidget SettingsScreen with Benachrichtigungen section, Android permission flow, DailyPlanDao-driven scheduling, notification tap navigation, and 5 widget tests

Performance

  • Duration: 5 min
  • Started: 2026-03-16T14:02:25Z
  • Completed: 2026-03-16T14:07:58Z
  • Tasks: 2
  • Files modified: 5

Accomplishments

  • SettingsScreen rewritten as ConsumerStatefulWidget with Benachrichtigungen section inserted between Darstellung and Uber
  • SwitchListTile with permission request on toggle ON: requestNotificationsPermission() called before state update; toggle stays OFF on denial with SnackBar
  • AnimatedSize progressive disclosure: time picker row only appears when notificationSettings.enabled is true
  • _scheduleNotification() queries DailyPlanDao for total/overdue counts; skips scheduling when total==0; builds conditional body with overdue split when overdue > 0
  • _onPickTime() opens Material 3 showTimePicker dialog and reschedules on selection
  • NotificationService._onTap wired to router.go('/') for notification tap navigation to Home tab
  • AppLocalizations regenerated with 7 notification strings from Plan 01 ARB file
  • 5 new widget tests: section header, toggle default OFF, time picker visible/hidden, formatted time display — all 89 tests pass

Task Commits

Each task was committed atomically:

  1. Task 1: Settings UI with Benachrichtigungen section, permission flow, and notification scheduling - 0103dde (feat)
  2. Task 2: Widget tests for notification settings UI - 77de7cd (feat)

Plan metadata: (docs commit — see final commit hash below)

Files Created/Modified

  • lib/features/settings/presentation/settings_screen.dart - ConsumerStatefulWidget with Benachrichtigungen section, permission flow, scheduling, and time picker
  • lib/core/notifications/notification_service.dart - Added router import and router.go('/') in _onTap
  • lib/l10n/app_localizations.dart - Regenerated abstract class with 7 new notification string declarations
  • lib/l10n/app_localizations_de.dart - Regenerated German implementations for 7 new notification strings
  • test/features/settings/settings_screen_test.dart - 5 widget tests covering notification UI states

Decisions Made

  • openNotificationSettings() unavailable: AndroidFlutterLocalNotificationsPlugin in v21.0.0 does not expose openNotificationSettings(). Simplified to informational SnackBar without action button. The ARB hint text already guides users to system settings manually.
  • ConsumerStatefulWidget: Chosen over ConsumerWidget because _onNotificationToggle and _scheduleNotification are async and require mounted checks after each await — this is only safe in State.
  • notificationSettingsProvider naming: Used notificationSettingsProvider (Riverpod 3 convention established in Plan 01), not notificationSettingsNotifierProvider as referenced in the plan interfaces section.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] openNotificationSettings() does not exist on AndroidFlutterLocalNotificationsPlugin v21

  • Found during: Task 1 (dart analyze after implementation)
  • Issue: Plan specified using androidPlugin?.openNotificationSettings() in the SnackBar action, but this method does not exist in flutter_local_notifications v21.0.0
  • Fix: Removed the action button from the SnackBar — simplified to an informational SnackBar showing notificationsPermissionDeniedHint text only. The plan explicitly offered "Pick the simpler approach: SnackBar with hint text" as an option.
  • Files modified: lib/features/settings/presentation/settings_screen.dart
  • Verification: dart analyze clean, no errors
  • Committed in: 0103dde

2. [Rule 1 - Bug] AppLocalizations missing notification string getters (stale generated files)

  • Found during: Task 1 (dart analyze)
  • Issue: app_localizations.dart and app_localizations_de.dart were not updated after Plan 01 added 7 strings to app_de.arb. The generated files were stale.
  • Fix: Ran flutter gen-l10n to regenerate localization files from ARB
  • Files modified: lib/l10n/app_localizations.dart, lib/l10n/app_localizations_de.dart
  • Verification: dart analyze clean after regeneration
  • Committed in: 0103dde

Total deviations: 2 auto-fixed (2 bugs — API mismatch and stale generated files) Impact on plan: Both auto-fixes were necessary. The SnackBar simplification is explicitly offered as the preferred option in the plan. The localization regeneration is a missing step from Plan 01 that Plan 02 needed.

Issues Encountered

  • flutter_local_notifications v21 API surface for AndroidFlutterLocalNotificationsPlugin does not include openNotificationSettings() — the plan referenced a method that was either added later or never existed in this version. Simplified to informational SnackBar per plan's own "simpler approach" option.

User Setup Required

None — no external service configuration required.

Next Phase Readiness

  • Phase 4 (Notifications) is fully complete: infrastructure (Plan 01) + Settings UI (Plan 02)
  • All 89 tests passing, dart analyze clean
  • Notification feature end-to-end: toggle ON/OFF, permission request, time picker, daily scheduling, tap navigation to Home

Phase: 04-notifications Completed: 2026-03-16
