I am trying to connect the Flutter demo app to firebase. I have been trying to follow a few different tutorials for this, and when I include these lines

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(const MyApp());
}

and run the app in chrome, I get a blank screen, as in the demo app never loads. Any ideas? I connected firebase to my app and copied the script into the index.html file, imported the firebase core package, added the dependency to the .yaml file, installed node js, and firebase login says I am already logged in
