android - Flutter - 我无法使用 Google 帐户登录

Question

当您点击该按钮时，会出现一个窗口，其中包含 Google 帐户选项，我选择了，但没有切换到新页面，而是出现错误。截图错误👇

我的代码:

import 'package:google_sign_in/google_sign_in.dart';

GoogleSignIn googleAuth = GoogleSignIn();
final FirebaseAuth _fAuth = FirebaseAuth.instance;
final GoogleSignIn _gSignIn = GoogleSignIn();

 Future<FirebaseUser> _signInGoogle() async {
    GoogleSignInAccount googleSignInAccount = await _gSignIn.signIn();
    GoogleSignInAuthentication authentication = await googleSignInAccount.authentication;

    var signInWithGoogle = signInWithGoogle;
    FirebaseUser user = await _fAuth.signInWithGoogle(
      idToken: authentication.idToken,
      accessToken: authentication.accessToken
    );
    return user;
  }


onPressed:() async {
  await _signInGoogle();                            
 Navigator.of(context).pushReplacementNamed('/home_screen');
}
