firebase - Flutter - Unhandled Exception: [core/duplicate-app]

Question

I am building a flutter app with firebase. The firebase services I am using are Realtime database and Authentication. The app is normally starting as usual without throwing any exception, but while I am hot restarting the app, the app freezes throwing the following exception:

Unhandled Exception: [core/duplicate-app] A Firebase App named "db2" already exists

I believe there's something wrong with initializing FirebaseApp. The initialization code in main.dart reads:

WidgetsFlutterBinding.ensureInitialized();
  final FirebaseApp app = await Firebase.initializeApp(
    name: 'db2',

Can somebody help me solve this issue? Thank you!
