android - 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。

我正在尝试使用 GoogleSignIn 登录和验证 Calender 范围。

我有-

• 使用 Android Studio 中的 gradle 任务获取我的 SHA-1 和 SHA256 指纹。
• 将 SHA-1 添加到我在 Google 云控制台中的 OAuth2 凭据。
• 将 SHA-1 和 SHA256 key 添加到我的 firebase 控制台
• 在这样做之后替换了 google-services.json 文件。
• 将 classpath 'com.google.gms:google-services:4.3.10' 添加到我项目的 build.gradle 文件中， 并在我的应用程序的 build.gradle 文件中 apply plugin: 'com.google.gms.google-services' 。
• 在所有这些之后运行 flutter clean。

我在手机和模拟器上都在调试和 Release模式下检查了它。

有谁知道我错过了什么吗？

这是我的代码:

这是在 initState() 中:

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

这是我按下登录按钮的时候:

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

这是我的 flutter doctor -v:

我还想添加额外的有用信息:

如果您对从 Google Play 管理中心 下载的应用Google 登录 有问题: 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
