谷歌使用 flutter 和 firebase auth 登录

Question

I am trying to implement Google Signin in my flutter app and I don't know what I am doing wrong, a little help is appriciated.

final GoogleSignIn googleSignIn = GoogleSignIn();
GoogleSignInAccount? currentUser;
googleLogin(context, color) async {
try {
  final googleUser = await googleSignIn.signIn();

  // loading(context, color);

  // I am not able to go beyond here
  
  if (googleUser == null) {
    Navigator.pop(context);
    return;
  }
  currentUser = googleUser;
  String? access, id;
  await googleUser.authentication.then((value) async {
    if (value != null) {
      access = value.accessToken;
      id = value.idToken;
    }
  });
  UserCredential userCredential = await FirebaseAuth.instance
      .signInWithCredential(
          GoogleAuthProvider.credential(idToken: id, accessToken: access));
  print('name: ${currentUser!.displayName}');
} catch (e) {}

}

I am stuck at the line, comment after that, what happens in the app is that dialogue box of accounts for google appears and when I select account, it disappears and nothing happens.

As for terminal, it displays

I realized I forgot to add SHA1 and SHA256 at firebase, added those and it worked.
