Question

我已经搜索了整个互联网，尝试了所有可能的解决方案，但仍然无法从Flutter应用中使用GoogleSignIn登录。

我尝试过的事情：
1.添加了SHA-1证书
2.添加了SHA-256证书
3.填写的O-Auth屏幕
4.在firebase中启用GoogleSignIn
5.添加了支持电子邮件

当前仅在调试模式下进行测试。由于该应用程序目前尚处于初始阶段，因此我不希望构建发行版本。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

Answer 1

我从Google官方文档中使用的过程给了我错误的SHA值。这篇文章帮助了我。这将给出与项目直接相关的SHA值。以下链接显示了如何从Android Studio获取SHA值。

Answer 2

我知道这个问题是在很久以前发布的，但是如果其他人遇到问题，除了上述所有步骤之外，我还启用了Google People API。确保您使用的是正确的电子邮件和项目。
