将 Firebase Auth 模拟器与 Flutter 结合使用时出现错误

Question

我在尝试通过 Firebase 模拟器使用 Google 登录时遇到此错误

[错误：flutter/runtime/dart_vm_initializer.cc(41)] 未处理的异常：[firebase_auth/unknown] 发生内部错误。 [ Auth 模拟器仅支持使用 id_token 而不是 access_token 登录 google.com。请更新您的代码以使用 id_token。

我的登录代码几乎是从 Firebase 文档中逐字复制的

import 'package:firebase_auth/firebase_auth.dart';
import 'package:google_sign_in/google_sign_in.dart';

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(
    accessToken: googleAuth?.accessToken,
    idToken: googleAuth?.idToken,
  );

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

这仅在连接到模拟器套件时显示，而不是在使用真实的 Firebase 实例时显示。

有解决方法或修复吗？

Firebase 集成是使用 FlutterFire CLI 初始化的

Answer 1

1. 首先检查 android/app/google-services.json 中的 json 文件

2. 在 Firebase 帐户中清除 Google 签名是否已禁用？

3. 最后更改 Firebase 控制台中的 ssh

试试这个-

./gradlew signingReport 

确保在 android 目录上运行特定命令
