onDidReceiveBackgroundNotificationResponse is never called at Android

[holailusoria]

onDidReceiveBackgroundNotificationResponse is never called at Android.

To Reproduce

1. Initialize flutter local notification plugin.
2. Move the application to the background.
3. Send push notification
4. Tap on push notification.
5. Logic in onDidReceiveBackgroundNotificationResponse(method as argument must have an annotation @pragma('vm:entry-point')) wasn't called.

Expected behavior
In step 5 described above method onDidReveiveBackgroundNotificationResponse has been called.

Sample code to reproduce the problem

final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
    FlutterLocalNotificationsPlugin();

@pragma('vm:entry-point')
void notificationTapBackground(NotificationResponse notificationResponse) {
  // ignore: avoid_print
  print('notification(${notificationResponse.id}) action tapped: '
      '${notificationResponse.actionId} with'
      ' payload: ${notificationResponse.payload}');
  if (notificationResponse.input?.isNotEmpty ?? false) {
    // ignore: avoid_print
    print(
        'notification action tapped with input: ${notificationResponse.input}');
  }
}

class test{
static initializePlugin() {
    try {
      final DarwinInitializationSettings initializationSettingsIOS =
          DarwinInitializationSettings(
              requestAlertPermission: true,
              requestBadgePermission: true,
              requestSoundPermission: true,
              onDidReceiveLocalNotification:
                  (int id, String? title, String? body, String? payload) async {
                // ignore: avoid_print
                print(
                    'Notification was receive: $title\nBody: $body\nPayload: $payload');
              });

      const AndroidInitializationSettings initializationSettingsAndroid =
          AndroidInitializationSettings('app_icon');

      final InitializationSettings initializationSettings =
          InitializationSettings(
        iOS: initializationSettingsIOS,
        android: initializationSettingsAndroid,
      );
      
      flutterLocalNotificationsPlugin.initialize(
          initializationSettings,
          onDidReceiveNotificationResponse: onDidReceiveNotificationResponse,
          onDidReceiveBackgroundNotificationResponse: notificationTapBackground,
        );
        catch (ex) {
      // ignore: avoid_print
      print('EXCEPTION: $ex');
    }
  }
}

I also cannot solve this problem, onDidReceiveBackgroundNotificationResponse is not triggered when notification is tapped

I'm having the same problem.
Has this been resolved problem?

This is expected behaviour, this callback is for notification actions and it's documented how you should deal with when a notification is tapped. Closing as it's a duplicate of #2134
