This repository is about implementing notifications in flutter app using Firebase backend service.

Build Status

After doing all the steps of integrating firebase into your project

Important packages to install:
  • firebase_messaging
  • firebase_core

Let's breakdown into code now:

  1. Add the following code into main method and make it asynchronous
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  1. Add this method at the global level to start firebase background serivces
Future<void> backgroundHandler(RemoteMessage message) async {}
  1. Add onBackgroundMessage callback method given by firebase in main method and pass above method in it
  FirebaseMessaging.onBackgroundMessage(backgroundHandler);
  1. Two important firebase methods to call whenever the app starts and best place to use them is in the initState callback of your main screen
    //called when app is in terminated state
    FirebaseMessaging.instance.getInitialMessage().then();
    
    //called when app is in foreground state
    FirebaseMessaging.onMessage.listen();
