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

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 登录并验证日历范围。

I have -

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

我在手机和模拟器上在调试和发布模式下检查了它。

有人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);
        }
      }
    });

这是当我按下登录按钮时：

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

这是我的flutter doctor -v:

我还想添加其他有用的信息：

如果您有问题谷歌登录对于从以下位置下载的应用程序谷歌游戏控制台: 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
