Firebase messaging background.

[domagojLumoLab]

I am actually cp code from firebase_messaging/example/lib/main and it is possible that notification received from firabase is duplicated when app is in background mode, specially with part of a code:
@pragma('vm:entry-point') Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async { await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform); await setupFlutterNotifications(); showFlutterNotification(message); // If you're going to use other Firebase services in the background, such as Firestore, // make sure you call initializeApp before using other Firebase services. print('Handling a background message ${message.messageId}'); }
because if we just put code like:
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async { await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform); } we will receive notification by default but not as heads up notification, so if we add showFlutterNotification(message); method, notifications will be duplicated. It is possible to avoid duplication or i misunderstood something? Thanks for answering.
