PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null) 尝试在 flutter 中使用 googleSignIn 时

Question

我已经阅读了我能找到的所有 Stackoverflow 问题和 github 问题，但没有任何效果。

\n

我正在尝试使用 GoogleSignIn 登录并验证日历范围。

\n

我有 -

\n

\n
• 使用 Android Studio 中的 gradle 任务来获取我的 SHA-1 和 SHA256 指纹。
\n
• 将 SHA-1 添加到 Google 云控制台中的 OAuth2 凭据中。
\n
• 将 SHA-1 和 SHA256 密钥添加到我的 Firebase 控制台
\n
• 执行此操作后替换了 google-services.json 文件。
\n
• 添加classpath 'com.google.gms:google-services:4.3.10'到我的项目的 build.gradle 文件中，\n以及apply plugin: 'com.google.gms.google-services' 我的应用程序的 build.gradle 文件中。
\n
• 追赶flutter clean这一切。
\n

\n

我在手机和模拟器上在调试和发布模式下检查了它。

\n

有人知道我错过了什么吗？

\n

这是我的代码：

\n

这是在 initState() 中：

\n

    _signIn.onCurrentUserChanged.listen((user) async {\n      if(user != null) {\n        d.log('${user.id}, ${user.email}, ${user.photoUrl}');\n        final authUser = (await _signIn.authenticatedClient());\n        if(authUser == null) {\n          d.log('no user');\n        } else {\n          _calendar = CalendarApi(authUser);\n        }\n      }\n    });\n

\n

这是当我按下登录按钮时：

\n

  void _onPress() {\n    if(_calendar == null) {\n      _signIn.signIn();\n    } else {\n      ...\n      });\n    }\n  }\n

\n

这是我的flutter doctor -v：

Answer 1

我还想添加其他有用的信息：

如果您在使用Google 登录从Google Play Console下载的应用时遇到问题：PlatformException(sign_in_failed, z1.b: 10: , null, null)

您需要将 SHA-1 从 Google Play 控制台添加到 Firebase
