PlatformException（sign_in_failed，com.google.android.gms.common.api.ApiException：10：，null）

Question

我搜索了整个互联网，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。

\n\n

我尝试过的事情：
\n1。添加了 SHA-1 证书
\n2。添加了 SHA-256 证书
\n3。已填充 O-Auth 屏幕
\n4. 在 firebase 中启用了 GoogleSignIn
\n5。添加了支持电子邮件

\n\n

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。

\n\n

Future<FirebaseUser> _signIn(BuildContext context) async {\nfinal GoogleSignInAccount googleUser = await _googleSignIn.signIn();\nfinal GoogleSignInAuthentication googleAuth =\n    await googleUser.authentication;\n\nfinal AuthCredential credential = GoogleAuthProvider.getCredential(\n    accessToken: googleAuth.accessToken, idToken: googleAuth.idToken);\n\nAuthResult userDetails =\n    await _firebaseAuth.signInWithCredential(credential);\nProviderDetails providerInfo = \nProviderDetails(userDetails.user.providerId);\n\nList<ProviderDetails> providerData = List<ProviderDetails>();\nproviderData.add(providerInfo);\n\nUserDetails details = UserDetails(\n    providerDetails: userDetails.user.providerId,\n    userEmail: userDetails.user.email,\n    userName: userDetails.user.displayName,\n    photoUrl: userDetails.user.photoUrl,\n    providerData: providerData);\n\nreturn userDetails.user;\n}\n

我知道这个问题是很久以前发布的，但为了防止其他人遇到问题，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。
