  <p>Edit 23.03.2022:</p>
  <p>it's because &quot;await Firebase.initializeApp();&quot; is called twice like in the documentation mentioned. i have to research more. maybe solution with firebase_options.dart.</p>

  <pre><code>Future&lt;void&gt; _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
    await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform,);
  }
  
  Future&lt;void&gt; main() async {
    WidgetsFlutterBinding.ensureInitialized();
    await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform,);
  
    // Set the background messaging handler early on, as a named top-level function
    FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
  
    //String? token =
    await FirebaseMessaging.instance.getAPNSToken();
    await FirebaseMessaging.instance.getToken();
    //print('APNS token: $token');
  }
