zonedSchedule notifications not sent

[gregorym]

Describe the bug
I am scheduling notifications (using zonedSchedule) in the future but all the notifications are stuck in pending and are never sent.
I can trigger notification immediately using show and it works as expected.

To Reproduce

  Future<void> _zonedScheduleNotification() async {
    try {
      int id = DateTime.now().millisecondsSinceEpoch.remainder(100000);
      tz.TZDateTime time =  tz.TZDateTime.now(tz.local).add(const Duration(seconds: 10));
      await flutterLocalNotificationsPlugin.zonedSchedule(
          id,
          'scheduled title',
          'scheduled body',
          time,
          const NotificationDetails(
              android: AndroidNotificationDetails(
                  'your channel id', 'your channel name',
                  importance: Importance.max,
                  priority: Priority.max,
                  showWhen: false,
                  channelDescription: 'your channel description')),
          payload: jsonEncode({'id': id, 'time': time.toString()}),
          androidScheduleMode: AndroidScheduleMode.inexactAllowWhileIdle,
          uiLocalNotificationDateInterpretation:
              UILocalNotificationDateInterpretation.absoluteTime);
    } catch (e) {
      print(e);
    }
  }

I am also logging all pending notifications right after:

  Future<void> _checkPendingNotificationRequests() async {
    final List<PendingNotificationRequest> pendingNotificationRequests =
        await flutterLocalNotificationsPlugin.pendingNotificationRequests();
    print('${pendingNotificationRequests.length} pending notification ');

    for (PendingNotificationRequest pendingNotificationRequest
        in pendingNotificationRequests) {
      print(pendingNotificationRequest.id.toString() +
          " " +
          (pendingNotificationRequest.payload ?? ""));
    }
    print('NOW ' + tz.TZDateTime.now(tz.local).toString());
  }

This is the logs:

I/flutter (18813): 96 {"id":96,"time":"2023-11-01 11:28:25.096493-0700"}
I/flutter (18813): 63018 {"id":63018,"time":"2023-11-01 11:34:28.019017-0700"}

I/flutter (18813): NOW 2023-11-01 11:40:23.148754-0700

I'm also initializing the timezones before running all this.

    tz.initializeTimeZones();
  final String? timeZoneName = await FlutterTimezone.getLocalTimezone();
  tz.setLocalLocation(tz.getLocation(timeZoneName!));

I can't figure out what is wrong...

@gregorym Did you find a solution for the problem? Having the same with Flutter 3.13.9 and flutter_local_notifications 16.1.0

I've a similar kind of issue where zoneScheduled notifications are not working as expected.Although it is working in future but only till my app is active in foreground or background.

[jaafar-shiha]

I was facing the same issue with flutter_local_notifications: ^16.1.0, Flutter version I have is 3.13.9, It is fixed in my case by adding this snippet of code to my AndroidManifest.xml inside application section, like the following:

<application>
  // your code
    <receiver
        android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver"
        android:exported="false" />
</application>

[gregorym]

I already had those 3 and it didn't work.

<receiver android:exported="false" android:name="${applicationId}.ActionBroadcastReceiver" />
<receiver android:exported="false" android:name="${applicationId}.ScheduledNotificationReceiver" />
<receiver android:exported="false" android:name="${applicationId}.ScheduledNotificationBootReceiver">

[rawi-coding]

Okay, I did oversee that part in the documentation when upgrading to version 16.

Previously the plugin would specify all the permissions required all of the features that the plugin support in its own AndroidManifest.xml file so that developers wouldn't need to do this in their own app's AndroidManifest.xml file. Since version 16 onwards, the plugin will now only specify the bare minimum

As said above, after adding the following to the AndroidManifest.xml, the ScheduledNotifications did appear again.

<receiver android:exported="false" android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver"/>
<receiver android:exported="false" android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
        <action android:name="android.intent.action.MY_PACKAGE_REPLACED"/>
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
    </intent-filter>
</receiver>

@gregorym I believe your problem is because you have ${applicationId}, which is different from what is in the readme and what @rawi-coding shows in their post. This ends causing the application to fail to locate the receivers as the wrong namespaces have been given

You were right, that was the issue. Thank you :)

When I tested it on an Android 9.0 device, the notification worked fine. However, when I tested it on an Android 14.0 device, it did not work.
I added the code below in the AndroidMainfest.xml file.

<receiver android:exported="false" android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationReceiver" />
        <receiver android:exported="false" android:name="com.dexterous.flutterlocalnotifications.ScheduledNotificationBootReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <action android:name="android.intent.action.MY_PACKAGE_REPLACED"/>
                <action android:name="android.intent.action.QUICKBOOT_POWERON" />
                <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
            </intent-filter>
        </receiver>

And this is the code for daily notification.

import 'package:flutter/material.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:timezone/data/latest.dart' as tz;
import 'package:timezone/timezone.dart' as tz;

class NotificationService {
  NotificationService(this.appStateRepository);

  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

  Future<void> init() async {
    tz.initializeTimeZones();

    const initializationSettingsAndroid = AndroidInitializationSettings('app_icon');

    const initializationSettings = InitializationSettings(
      android: initializationSettingsAndroid,
    );

    await flutterLocalNotificationsPlugin.initialize(
      initializationSettings,
    );
  }

  Future<void> scheduleDailyNotification(int id, String message, TimeOfDay timeOfDay) async {
    final now = DateTime.now();
    final scheduledDate = _nextInstanceOfTime(timeOfDay, now);

    const androidDetails = AndroidNotificationDetails(
      '0',
      'notification',
      channelDescription: 'Daily Notification',
      importance: Importance.high,
      largeIcon: DrawableResourceAndroidBitmap('notification_icon'),
    );

    const notificationDetails = NotificationDetails(android: androidDetails);

    await flutterLocalNotificationsPlugin.zonedSchedule(
      id,
      'Notification',
      message,
      scheduledDate,
      notificationDetails,
      androidAllowWhileIdle: true,
      uiLocalNotificationDateInterpretation: UILocalNotificationDateInterpretation.wallClockTime,
      matchDateTimeComponents: DateTimeComponents.time,
    );
  }

  tz.TZDateTime _nextInstanceOfTime(TimeOfDay timeOfDay, DateTime now) {
    final scheduledDate = tz.TZDateTime(tz.local, now.year, now.month, now.day, timeOfDay.hour, timeOfDay.minute);

    if (scheduledDate.isBefore(now)) {
      return scheduledDate.add(const Duration(days: 1));
    }
    return scheduledDate;
  }

  Future<void> handleAppOpen(List<String> messages) async {
    await flutterLocalNotificationsPlugin.cancelAll();

    final messageIndex = 1;
    final lastOpenedDate = db.lastOpenedDate ?? DateTime.now();
    final dailyTime = TimeOfDay(hour: lastOpenedDate.hour, minute: 0);

    await scheduleDailyNotification(0, messages[messageIndex], dailyTime);
  }
}

I didn't find the why yet. Please help me.

@jiayixu420 I was having your same problem. I realised I had forgot to ask for Notification permissons:

    _notificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()!
        .requestNotificationsPermission();

This issue hasn't been resolved, and it fails to even show a zoned schedule notification on ios
