--- phase: 04-notifications verified: 2026-03-16T15:00:00Z status: passed score: 21/21 must-haves verified re_verification: false --- # 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.

All requirements mapped to Phase 4 in REQUIREMENTS.md (NOTF-01, NOTF-02) are claimed and satisfied by the phase plans. --- ### Anti-Patterns Found No anti-patterns found. Scanned: - `lib/core/notifications/notification_service.dart` - `lib/core/notifications/notification_settings_notifier.dart` - `lib/features/settings/presentation/settings_screen.dart` No TODOs, FIXMEs, placeholder comments, empty implementations, or stub handlers detected. --- ### 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 `FlutterLocalNotificationsPlugin` with TZ-aware scheduling, permission request, and cancel. - **NotificationSettingsNotifier** persists `enabled`, `hour`, and `minute` to 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 `ConsumerStatefulWidget` with 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: `_onTap` in NotificationService imports the top-level `router` and calls `router.go('/')`. - **All 7 ARB keys** are present in `app_de.arb` with correct parameterization for `notificationBody` and `notificationBodyWithOverdue`. - **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. --- _Verified: 2026-03-16T15:00:00Z_ _Verifier: Claude (gsd-verifier)_
