dart - Firebase 身份验证无法在我的颤振应用中使用谷歌登录

Question

我在我的 Flutter 应用程序中使用了 firebase-auth 和 google-signin，当点击“使用 Google 登录”按钮时，会打开一个 google 弹出窗口，以便我可以选择我想要使用的 google 帐户，当我点击在我的帐户上，弹出关闭，我在我的控制台中有这个：

D/ViewRootImpl@8929a4d[SignInHubActivity](25903): MSG_WINDOW_FOCUS_CHANGED 1
V/InputMethodManager(25903): Starting input: tba=android.view.inputmethod.EditorInfo@c535c6f nm : com.youpa.youpa ic=null

而且我没有登录。但是，我的带有电子邮件的 firbase 身份验证系统运行良好。在这里，您有我的 Google 登录按钮的 onPressed ：

onPressed: () {
              Auth()
                  .handleSignInWithGoogle()
                  .then((FirebaseUser user) {
              }).catchError((e) {
                print("Error : " +
                    internationalization
                        .text("firebase_error." + e.code));
              });
            },

在这里，您有我的身份验证服务的某些部分：

import 'package:firebase_auth/firebase_auth.dart';
import 'package:firebase_storage/firebase_storage.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:youpa/Model/user.model.dart';
import 'package:firebase_core/firebase_core.dart';
import 'options.services.dart';
import 'package:google_sign_in/google_sign_in.dart';
import 'package:shared_preferences/shared_preferences.dart';
import 'dart:io';

class Auth {
  final GoogleSignIn googleSignIn = GoogleSignIn(
    scopes: [
      'email',
      'https://www.googleapis.com/auth/contacts.readonly',
      'profile'
    ],
  );
  final FirebaseAuth firebaseAuth = FirebaseAuth.instance;
  SharedPreferences prefs;
  final FirebaseAuth auth = FirebaseAuth.instance;

  Future<FirebaseUser> handleSignInWithGoogle() async {
    final GoogleSignInAccount googleUser = await googleSignIn.signIn();
    final GoogleSignInAuthentication googleAuth = await googleUser.authentication;
    final AuthCredential credential = GoogleAuthProvider.getCredential(
      accessToken: googleAuth.accessToken,
      idToken: googleAuth.idToken,
    );
    FirebaseUser user = await auth.signInWithCredential(credential);
    assert(user.email != null);
    assert(user.displayName != null);
    assert(!user.isAnonymous);
    assert(await user.getIdToken() != null);

    final FirebaseUser currentUser = await auth.currentUser();
    assert(user.uid == currentUser.uid);
    print(user);
    print(currentUser);

    return user;
  }
}

你知道错误在哪里吗？提前致谢。杰里米。
