How to handle tapping local notification when app is terminated in Flutter?

Question

I am using flutter_local_notifications plugin to show notifications in Flutter and here is the initialization code:

Future<void> initializePlatformNotifications() async {
const AndroidInitializationSettings initializationSettingsAndroid = AndroidInitializationSettings('icon');

final DarwinInitializationSettings initializationSettingsIOS = DarwinInitializationSettings(
    requestSoundPermission: true,
    requestBadgePermission: true,
    requestAlertPermission: true,
    onDidReceiveLocalNotification: onDidReceiveLocalNotification);

final InitializationSettings initializationSettings = InitializationSettings(
  android: initializationSettingsAndroid,
  iOS: initializationSettingsIOS,
);

await flutterLocalNotificationsPlugin.initialize(
  initializationSettings,
  onDidReceiveNotificationResponse: (NotificationResponse notificationResponse) {
    behaviorSubject.add(notificationResponse.payload!);
    
  },
  onDidReceiveBackgroundNotificationResponse: notificationTapBackground,
);

}

the above code is working and the onDidReceiveNotificationResponse callback is called when the notification is clicked when the app is in the background but when the app is terminated and I click on the notification the callback is not called.

Should I use a different callback or my initialization code is missing something?

Answer 1

If your app is launched from terminated state by clicking on notification, you can get NotificationResponse via

flutterLocalNotificationsPlugin.getNotificationAppLaunchDetails()

onDidReceiveNotificationResponse only called when your app is paused, not terminated.
