How to get second FirebaseCrashlytics.instance by name?

#flutter #dart #firebase_crashlytics #multipleinstances

I am using FirebaseCrashlytics in a Flutter app. I am in need of create two Firebase instance, one for native Android with
"[DEFAULT]" name, and the other customized with name "FlutterFirebaseInstance"

My setup:

firebase_core: ^2.14.0  
firebase_crashlytics: ^3.3.3

Implementation in Dart as follows:

  const String instanceName = 'FlutterFirebaseInstance';

  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    name: instanceName,
    options: DefaultFirebaseOptions.currentPlatform, // taking from firebase_options.dart
  );

then verify by printing apps via Firebase.app

  print('all firebase apps: ${Firebase.app(instanceName)}');
// ![image](https://github.com/firebase/flutterfire/assets/49189269/c249243e-459c-4fc6-8aff-d130d1ec56c2)

But I got no idea how to get FirebaseCrashlytics of this custom instance (my instance). Basically FirebaseCrashlytics.instance return the instance of name "[DEFAULT]" . So whenever to call FirebaseCrashlytics.instance.recordError(...), the report goes to the host application rather than what is defined in my firebase_options.dart file.

FirebaseCrashlytics.instance.recordError(...)

I checked FirebaseCrashlytics source code, but there's literally no way. Is it a bug or a soon-to-be-implemented feature?

Does anyone have any idea on how to get the instance of the second FirebaseCrashlytics?

@ndnam198 hi there, I have the same problem here. I'm using flavors in Flutter and I have 2 instances of Firebase app but I can't get the specific crashlytics instance for each app and it's not reporting error as well
