How to handle click on push-notification when application is in foreground?

Question

I use the Firebase Cloud Messaging (FCM) in my Flutter project. The following packages:

firebase_messaging: ^8.0.0-dev.15
flutter_local_notifications: ^4.0.1+2

I know that I can handle click on push-notification when app is in background in the following way:

FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
      //TODO
    });

and it works fine, but how to handle click on push-notification when application is in foreground? Can't find in the documentation as well. Could you please help me. Thanks in advance.

Answer 1

Use this dependency when the app is in foreground- https://pub.dev/packages/flutter_local_notifications

Edit

FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
      //TODO
    });

You are already using this code for when the app is in background. See that you are using onMessageOpenedApp. For firing the message when in foreground you can use onMessage. Example-

FirebaseMessaging.onMessage.listen((message) { 
 LocalNotificationService.display(message);
});

Answer 2

you can set the callback function on initializing

await flutterLocalNotificationsPlugin.initialize(
  const InitializationSettings(
    android: initializationSettingsAndroid,
    iOS: initializationSettingsIOS,
  ),
  onSelectNotification: handleClickNotification,
);

handleClickNotification(String? payload) {
  //your code
}
