Phase 4: Notifications Verification Report
Phase Goal: Users receive a daily summary notification reminding them of today's task count, and can control notification behavior from settings Verified: 2026-03-16T15:00:00Z Status: PASSED Re-verification: No — initial verification
Goal Achievement
Observable Truths
All must-haves are drawn from the PLAN frontmatter of plans 01 and 02. Plan 03 is a verification-gate plan (no truths, no artifacts) and contributes no additional must-haves.
Plan 01 Must-Haves
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | NotificationService can schedule a daily notification at a given TimeOfDay | VERIFIED | scheduleDailyNotification in notification_service.dart lines 30-55; uses zonedSchedule |
| 2 | NotificationService can cancel all scheduled notifications | VERIFIED | cancelAll() delegates to _plugin.cancelAll() at line 57 |
| 3 | NotificationService can request POST_NOTIFICATIONS permission | VERIFIED | requestPermission() resolves AndroidFlutterLocalNotificationsPlugin, calls requestNotificationsPermission() |
| 4 | NotificationSettingsNotifier persists enabled boolean and TimeOfDay to SharedPreferences | VERIFIED | setEnabled and setTime each call SharedPreferences.getInstance() and persist values |
| 5 | NotificationSettingsNotifier loads persisted values on build | VERIFIED | build() calls _load() which reads SharedPreferences and overrides state asynchronously |
| 6 | DailyPlanDao can return a one-shot count of overdue + today tasks | VERIFIED | getOverdueAndTodayTaskCount and getOverdueTaskCount present in daily_plan_dao.dart lines 36-55 |
| 7 | Timezone is initialized before any notification scheduling | VERIFIED | main.dart: tz.initializeTimeZones() → FlutterTimezone.getLocalTimezone() → tz.setLocalLocation() → NotificationService().initialize() |
| 8 | Android build compiles with core library desugaring enabled | VERIFIED | build.gradle.kts line 14: isCoreLibraryDesugaringEnabled = true; line 48: coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.1.4") |
| 9 | AndroidManifest has POST_NOTIFICATIONS permission, RECEIVE_BOOT_COMPLETED permission, and boot receiver | VERIFIED | Lines 2-4: both permissions; lines 38-48: ScheduledNotificationReceiver (exported=false) and ScheduledNotificationBootReceiver (exported=true) with BOOT_COMPLETED intent-filter |
Plan 02 Must-Haves
| # | Truth | Status | Evidence |
|---|---|---|---|
| 10 | Settings screen shows a Benachrichtigungen section between Darstellung and Uber | VERIFIED | settings_screen.dart lines 144-173: section inserted between Divider after Darstellung and Divider before Uber |
| 11 | SwitchListTile toggles notification enabled/disabled | VERIFIED | Line 156: SwitchListTile with value: notificationSettings.enabled and onChanged: _onNotificationToggle |
| 12 | When toggle is ON, time picker row appears below with progressive disclosure animation | VERIFIED | Lines 162-171: AnimatedSize wrapping conditional ListTile when notificationSettings.enabled is true |
| 13 | When toggle is OFF, time picker row is hidden | VERIFIED | Same AnimatedSize: returns SizedBox.shrink() when disabled; widget test confirms find.text('Uhrzeit') finds nothing |
| 14 | Tapping time row opens Material 3 showTimePicker dialog | VERIFIED | _onPickTime() at line 78 calls showTimePicker with initialEntryMode: TimePickerEntryMode.dial |
| 15 | Toggling ON requests POST_NOTIFICATIONS permission on Android 13+ | VERIFIED | _onNotificationToggle(true) immediately calls NotificationService().requestPermission() before state update |
| 16 | If permission denied, toggle reverts to OFF | VERIFIED | Lines 23-34: if !granted, SnackBar shown and early return — setEnabled is never called, state stays off |
| 17 | If permanently denied, user is guided to system notification settings | VERIFIED | SnackBar message notificationsPermissionDeniedHint tells user to go to system settings. Note: no action button (simplified per plan's "simpler approach" option — v21 has no openNotificationSettings()) |
| 18 | When enabled + time set, daily notification is scheduled with correct body from DAO query | VERIFIED | _scheduleNotification() lines 49-76: queries getOverdueAndTodayTaskCount and getOverdueTaskCount, builds body, calls scheduleDailyNotification |
| 19 | Skip notification scheduling when task count is 0 | VERIFIED | Lines 58-62: if total == 0, calls cancelAll() and returns without scheduling |
| 20 | Notification body shows overdue count only when overdue > 0 | VERIFIED | Lines 66-68: overdue > 0 uses notificationBodyWithOverdue(total, overdue), else notificationBody(total) |
| 21 | Tapping notification navigates to Home tab | VERIFIED | notification_service.dart line 79: _onTap calls router.go('/') using top-level router from router.dart |
Score: 21/21 truths verified

Human Verification Required
The following behaviors require a physical Android device or emulator to verify:
1. Permission Grant and Notification Scheduling
Test: Install app on Android 13+ device. Navigate to Settings. Toggle "Tagliche Erinnerung" ON.
Expected: Android system permission dialog appears. After granting, the time row appears with the default 07:00 time.
Why human: requestPermission() dispatches to the Android plugin at native level — cannot be exercised without a real Android environment.
2. Permission Denial Flow
Test: On Android 13+, toggle ON, then deny the system permission dialog. Expected: Toggle remains OFF. A SnackBar appears with "Benachrichtigungen sind in den Systemeinstellungen deaktiviert. Tippe hier, um sie zu aktivieren." Why human: Native permission dialog interaction requires device runtime.
3. Daily Notification Delivery
Test: Enable notifications, set a time 1-2 minutes in the future. Wait. Expected: A notification titled "Dein Tagesplan" appears in the system tray at the scheduled time with a body showing today's task count (e.g. "3 Aufgaben fallig"). Why human: Notification delivery at a scheduled TZDateTime requires actual system time passing.
4. Notification Tap Navigation
Test: Tap the delivered notification from the system tray while the app is in the background.
Expected: App opens (or foregrounds) directly to the Home/Daily Plan tab.
Why human: _onTap with router.go('/') requires the notification to actually arrive and the app to receive the tap event.
5. Boot Receiver
Test: Enable notifications on a device, reboot the device.
Expected: Notification continues to fire at the scheduled time after reboot (rescheduled by ScheduledNotificationBootReceiver).
Why human: Requires physical device reboot with the notification enabled.
Summary
Phase 4 goal is achieved. All 21 observable truths from the plan frontmatter are verified against the actual codebase:
- NotificationService is a complete, non-stub singleton wrapping
FlutterLocalNotificationsPluginwith TZ-aware scheduling, permission request, and cancel. - NotificationSettingsNotifier persists
enabled,hour, andminuteto SharedPreferences using the@Riverpod(keepAlive: true)pattern, following the established ThemeNotifier convention. - DailyPlanDao has two real Drift queries (
getOverdueAndTodayTaskCount,getOverdueTaskCount) that count tasks for the notification body. - Android build is fully configured: compileSdk=35, core library desugaring enabled, POST_NOTIFICATIONS + RECEIVE_BOOT_COMPLETED permissions, and both receivers registered in AndroidManifest.
- main.dart correctly initializes timezone data and sets the local location before calling
NotificationService().initialize(). - SettingsScreen is a
ConsumerStatefulWidgetwith a Benachrichtigungen section (SwitchListTile + AnimatedSize time picker) inserted between the Darstellung and Uber sections. The permission flow, scheduling logic, and skip-on-zero behavior are all substantively implemented. - Notification tap navigation is wired:
_onTapin NotificationService imports the top-levelrouterand callsrouter.go('/'). - All 7 ARB keys are present in
app_de.arbwith correct parameterization fornotificationBodyandnotificationBodyWithOverdue. - 89/89 tests pass and dart analyze --fatal-infos reports zero issues.
- NOTF-01 and NOTF-02 are fully satisfied. No orphaned requirements.
Five items require human/device verification (notification delivery, permission dialog, tap navigation, boot receiver) as they depend on Android runtime behavior that cannot be verified programmatically.
