"At least one of ID token and access token is required" with google signin flow with firebase emulator suite

Question

I am trying to test google signin flow with firebase emulator suite. The issue is google sign-in are not receive idToken all the time but firebase emulator suite only supports id_token, So I can't login through this approach.

Edited:

 Future<UserCredential> signInWithGoogle() async {
    // Trigger the authentication flow
    final GoogleSignInAccount? googleUser = await GoogleSignIn().signIn();

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

    // Create a new credential
    final credential = GoogleAuthProvider.credential(
      // Didn't fill accessToken arg cause firebase emulator only supports idToken.
      // accessToken: googleAuth?.accessToken,
      idToken: googleAuth?.idToken,
    );

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

I get this error 'accessToken != null || idToken != null': At least one of ID token and access token is required when call GoogleAuthProvider.credential, With accessToken I am able to login on real firebase project successfully and both are tested in debug mode with API 31 Emulator, So SHA-1 should been set successfully.

Google sign-in version google_sign_in: ^5.4.0

Flutterfire cli doc says:

if your Flutter app supports Android then the Android Google Services Gradle plugin will automatically be applied for you.

But seems it's not working for me, I have tried 0.2.0 and 0.2.4 both didn't add google-services plugin for me. So just add it manually.
