It is asking for Fabric in Firebase Crashlytics.

I get exception when setup this plugin:

This app relies on Crashlytics. Please sign up for access at https://fabric.io/sign_up,
install an Android build tool and ask a team member to invite you to this app's organization.

I am using only Firebase Crashlytics and not Fabric. Am I supposed to use both, I guess not.

Steps I followed.

• Create android app on firebase
• Save google-services.json file in app folder.
• Install plugin
• Change main() to below snippet

void main() async {
  bool isInDebugMode = false;

  FlutterError.onError = (FlutterErrorDetails details) {
    if (isInDebugMode) {
      // In development mode simply print to console.
      FlutterError.dumpErrorToConsole(details);
    } else {
      // In production mode report to the application zone to report to
      // Crashlytics.
      Zone.current.handleUncaughtError(details.exception, details.stack);
    }
  };

  await FlutterCrashlytics().initialize();

  runZoned<Future<Null>>(() async {
    runApp(MyApp());
  }, onError: (error, stackTrace) async {
    // Whenever an error occurs, call the `reportCrash` function. This will send
    // Dart errors to our dev console or Crashlytics depending on the environment.
    await FlutterCrashlytics()
        .reportCrash(error, stackTrace, forceCrash: false);
  });
}
