firebase authentication google sign in not working when I run my flutter web app in wasm mode, it is working fine in html and canvas kit renderer

[vrajkishore]

I am listening to authstate changes using the listenToUserChanges() function and performing google sign in using the createGoogleAuthCustomer() function, in normal rendered I am able to listen to the FirebaseAuth.instance.authStateChanges() when I perform the google sign in a popup, in wasm even though I continue with google sign in the popup not able to listen to the FirebaseAuth.instance.authStateChanges() and also not able to find the error

import 'package:firebase_auth/firebase_auth.dart';

Stream<User?> listenToUserChanges() async* {
await for (var user in FirebaseAuth.instance.authStateChanges()) {
yield user;
}
}

Future createGoogleAuthCustomer() async {
try {
GoogleAuthProvider googleProvider = GoogleAuthProvider();
// googleProvider
// .addScope('https://www.googleapis.com/auth/contacts.readonly');
// googleProvider.setCustomParameters({'login_hint': '[email protected]'});
return await FirebaseAuth.instance.signInWithPopup(googleProvider);

} catch (e) {
  throw CustomException(AuthDataRepository, "Authentication failed",
      displayMessage: "Failed to authenticate with Google.");
}

}

Hi there, I tested out google sign in on our example authentication app in wasm mode and it worked perfectly fine and successfully checked persisted user data. I would suggest checking out how we implemented it here as maybe there is an issue with your implementation: https://github.com/firebase/flutterfire/tree/main/packages/firebase_auth/firebase_auth/example
