firebaseAuth. signInWithCredential(credential) return error

[armanhadifatah]

Bug report

Using firebase auth for google sign in but when I call _firebaseAuth.signInWithCredential(credential) , I get this weird error

_TypeError (type 'List<Object?>' is not a subtype of type 'int?' in type cast)

this is my code

  Future<UserCredential> signInWithGoogle() async {
    final GoogleSignInAccount? googleUser = await GoogleSignIn().signIn();
    final GoogleSignInAuthentication? googleAuth =
        await googleUser?.authentication;
    final credential = GoogleAuthProvider.credential(
      accessToken: googleAuth?.accessToken,
      idToken: googleAuth?.idToken,
    );
    return await _firebaseAuth.signInWithCredential(credential);
  }

This was working before but it has been a day or two it doesn't work

@armanhadifatah
The plugin example has below implementation. Please check the same in your case and see if it helps in your case or not:

Future<void> _signInWithGoogle() async {
    // Trigger the authentication flow
    final googleUser = await GoogleSignIn().signIn();

    // Obtain the auth details from the request
    final googleAuth = await googleUser?.authentication;

    if (googleAuth != null) {
      // Create a new credential
      final credential = GoogleAuthProvider.credential(
        accessToken: googleAuth.accessToken,
        idToken: googleAuth.idToken,
      );

      // Once signed in, return the UserCredential
      await auth.signInWithCredential(credential);
    }
  }

Your code is the same as mine , Like i said it was working and I didn't touch any thing , but now I get that error , if the error is with configuration or any thing else it should give me the error not
_TypeError (type 'List<Object?>' is not a subtype of type 'int?' in type cast)

even if the error from myside this shouldn't be the error message

I did a pub cache clean

And added in pubspec

dependency_overrides:
  firebase_auth_platform_interface: 6.18.0

Now it works

I am unable to replicate the reported error using plugin example with latest firebase_auth and firebase_core versions running on Android emulator. I was able to login with test account properly as below:

@sbenmeddour You seem to be using specific versions of the listed plugins. Can you try with ^ ?

@armanhadifatah What plugin version are you using ?
