after updating Android Studio and flutter (and kotlin) i get this warnings/errors

how to solve or can i ignore without consequential error?

Thank you in anvance.

W/FlutterJNI(23046): FlutterJNI.loadLibrary called more than once
W/FlutterJNI(23046): FlutterJNI.prefetchDefaultFontManager called more than once
W/FlutterJNI(23046): FlutterJNI.init called more than once

Edit 23.03.2022:

it's because "await Firebase.initializeApp();" is called twice like in the documentation mentioned. i have to research more. maybe solution with firebase_options.dart.

enter image description here

Edit 16.04.2022:

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform,);
}

Future<void> 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');
}

  • I had the same issue when I was trying some stuff out with firebase messaging. Unfortunately I couldnt find a fix and went back to flutter 2.8.1 :/ – Aknahseh_tg Mar 22 '22 at 11:46
  • if i remove all firebase lines from source code, the error is gone. i tried older versions of both plugins without success (firebase_messaging, firebase_core). – AlexF1 Mar 23 '22 at 19:09
  • the creation of the firebase_options.dart file didn't help. still the same error. https://stackoverflow.com/questions/70404936/missing-firebase-options-dart-file-in-course-get-to-know-firebase-for-flutter – AlexF1 Mar 28 '22 at 13:56

I was facing the same error. This message shows if you call FirebaseMessaging.instance multiple times. For Example:

final _firebaseMessaging = FirebaseMessaging.instance
await _firebaseMessaging.requestPermission(
  announcement: true,
  carPlay: true,
  criticalAlert: true,
);
await

FirebaseMessaging.instance.setForegroundNotificationPresentationOptions( alert: true, badge: true, sound: true, );

So here, the FirebaseMessaging.instance is called twice. Solved by changing FirebaseMessaging.instance to _firebaseMessaging. Hope this might help.

Note: Do not use FirebaseMessaging.instance in differenta files, or use it by passing the initialized one.
