FirebaseOptions cannot be null when creating the default app flutter-CodePudding

I am trying to run a flutter app locally on my web browser (chrome). I do the following steps:

flutter channel stable
flutter config --enable-web
flutter run -d chrome

when I run it, it starts fine, and opens chrome but it doesn't load anything, and then throws this error:

"FirebaseOptions cannot be null when creating the default app."

how would I fix this?

edit:

void main() async{


WidgetsFlutterBinding.ensureInitialized();
  setPathUrlStrategy();
  await Firebase.initializeApp();

You can reference the Flutter Firebase setup steps here:

You will use DefaultFirebaseOptions.currentPlatform
