PlatformException（登录失败，com.google.android.gms.common.api.ApiException:10:，null）

Question

我已经搜索了整个互联网，尝试了所有可能的解决方案，但我仍然无法从我的flutter应用程序中使用GoogleSignIn登录。

我尝试过的事情：
1。添加SHA-1证书
2.添加SHA-256证书
3.填充的O-Auth屏幕
4.在Firebase中启用GoogleSignIn
5.添加支持电子邮件

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;
}

我犯了一个错误

Answer 1

添加依赖项后重建项目了吗？

有时，在有效使用任何平台特定插件之前，您需要在添加任何平台特定插件时重新构建项目

我知道这个问题是很久以前发布的，但如果其他人有问题，除了上述所有步骤外，我还启用了Google People API。确保您的电子邮件和项目正确。
