【问题描述】：
我已经搜索了整个互联网，尝试了所有可能的解决方案，但我仍然无法从我的 Flutter 应用中使用 GoogleSignIn 登录。
我尝试过的事情：
1. 新增 SHA-1 证书
2. 新增 SHA-256 证书
3. 填写 O-Auth 屏幕
4. 在 Firebase 中启用 GoogleSignIn
5. 增加支持邮箱
目前仅在调试模式下进行测试。由于该应用程序目前处于初始阶段，我还不想构建发布版本。使用调试 SHA-1 和 SHA-256 指纹。
Future<FirebaseUser> _signIn(BuildContext context) async {
final GoogleSignInAccount googleUser = await _googleSignIn.signIn();
final GoogleSignInAuthentication googleAuth =
await googleUser.authentication;
final AuthCredential credential = GoogleAuthProvider.getCredential(
accessToken: googleAuth.accessToken, idToken: googleAuth.idToken);
AuthResult userDetails =
await _firebaseAuth.signInWithCredential(credential);
ProviderDetails providerInfo =
ProviderDetails(userDetails.user.providerId);
List<ProviderDetails> providerData = List<ProviderDetails>();
providerData.add(providerInfo);
UserDetails details = UserDetails(
providerDetails: userDetails.user.providerId,
userEmail: userDetails.user.email,
userName: userDetails.user.displayName,
photoUrl: userDetails.user.photoUrl,
providerData: providerData);
return userDetails.user;
}
我得到错误
