core/no-app No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()-CodePudding

When I try to launch my Flutter Web App with Firebase I get the following error in my terminal

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following FirebaseException was thrown building HomePage(dirty, dependencies: [MediaQuery]):
[core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()

The relevant error-causing widget was:
  HomePage HomePage:file:///C:/Flutter/pbwebapp/lib/main.dart:37:13

When the exception was thrown, this was the stack:
...

I found other people had problems with this error but in my case I have called Firebase.initializeApp() in my main.dart file and I have also imported firebase_core in my pubspec.yaml

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    name: "pbwebapp",
    options: const FirebaseOptions(
      apiKey: "...",
      authDomain: "..",
      projectId: "...",
      storageBucket: "...",
      messagingSenderId: "...",
      appId: "...",
      measurementId: "...",
    ),
  );
  runApp(MyApp());
}

Does anyone had this problem with Firebase trying to launch a Flutter Web App? Thanks in advance!

Use Flutter Fire Cli to add flutter firebase packages like auth, messaging etc, It will automatically configure all the things for you.

Okay so somehow removing the name parameter in the Firebase.initializeApp() function worked for me. But I dont know why exactly
