both firebase and flutter local notifications handle background notificaiton
185
Solution 1
- One possible problem is the initialization of your local_notification_package
It should be a topmost initialization, i.e you initialize the flutter_local_notifications
package and the android channel before calling _showNotification
function
- Another possible problem is the initialization of firebase. It should be done before the app runs, since it is a foreground notification
Solution 2
Your firebaseMessagingBackgroundHandler will look like.......
Future<void> firebaseMessagingBackgroundHandler(RemoteMessage? message) async {
await Firebase.initializeApp(); //initialize firebase
//INITIALIZE YOUR FLUTTER LOCAL NOTIFICATION PACKAGE
// INITIALIZE YOUR ANDROID CHANNEL
//then show the notification
_showNotification(
id: 0,
title: message?.notification?.title ?? '',
body: message?.notification?.body ?? '');
}

I'm facing an issue with displaying double notifications when the app in the background firebase handle the notification first and then the flutter local notification display a popup on the screen anyway to make firebase not show the notification
p.s remove the
FirebaseMessaging.onBackgroundMessage(firebaseMessagingBackgroundHandler);make the app not handle notifications on background
FirebaseMessaging.onMessage.listen( (RemoteMessage? message) async { _showNotification( id: 0, title: message?.notification?.title ?? '', body: message?.notification?.body ?? ''); }, ); FirebaseMessaging.onBackgroundMessage(firebaseMessagingBackgroundHandler);
firebaseMessagingBackgroundHandler:
Future<void> firebaseMessagingBackgroundHandler(RemoteMessage? message) async { _showNotification( id: 0, title: message?.notification?.title ?? '', body: message?.notification?.body ?? ''); }
the firebase package contains title and body in the notification flag even if the app working in the background any way to make the notification only handled by flutter_local_notification package
