我们正在使用Flutter构建一个移动的应用程序，它可以读取睡眠数据并显示基于睡眠数据的 Jmeter 板，
我们正在使用Firebase进行社交登录。目前，我们支持谷歌，Facebook和自定义电子邮件/基于密码的登录。

谷歌登录

当用户使用Google帐户登录时，应用程序将获取睡眠数据。我们正在传递Google API范围，如下所示。

FirebaseAuth.instance, UserRepository(), GoogleSignIn(scopes:[
'https://www.googleapis.com/auth/fitness.sleep.read',
])),

Facebook登录

如果用户使用Facebook帐户登录，我们会收到以下错误。不知道如何在Facebook登录中传递Google API范围。我收到下面的问题：

W/FLUTTER_HEALTH::ERROR(31643): There was an error getting the sleeping data!
W/FLUTTER_HEALTH::ERROR(31643): 4: The user must be signed in to make this API call.
W/FLUTTER_HEALTH::ERROR(31643): [Ljava.lang.StackTraceElement;@7eb1aa0
W/FLUTTER_HEALTH::ERROR(31643): There was an error getting the sleeping data!

请看一下我们使用的代码：

`Future fetchSleepData() async {
     List<HealthDataPoint> _healthDataList = [];
    final types = [
      HealthDataType.SLEEP_ASLEEP,
      HealthDataType.SLEEP_AWAKE,
      HealthDataType.SLEEP_IN_BED
    ];

    final permissions = [
      HealthDataAccess.READ,
      HealthDataAccess.READ,
      HealthDataAccess.READ
    ];
    final now = DateTime.now();
    final yesterday = now.subtract(Duration(days: 10));
    HealthFactory health = HealthFactory();
    bool requested =
        await health.requestAuthorization(types, permissions: permissions);
    await Permission.activityRecognition.request();
    await Permission.location.request();
    if (requested) {
      try {
        // fetch health data
        List<HealthDataPoint> healthData =
            await health.getHealthDataFromTypes(yesterday, now, types);
        // save all the new data points (only the first 100)
        _healthDataList.addAll((healthData.length < 100)
            ? healthData
            : healthData.sublist(0, 100));
      } catch (error) {
        print("Exception in getHealthDataFromTypes: $error");
      }
      // filter out duplicates
      _healthDataList = HealthFactory.removeDuplicates(_healthDataList);
      // print the results
      _healthDataList.forEach((x) => print(x));
    }
  }`

请帮助我使用Flutter Firebase从Google API读取睡眠数据。用户使用Facebook Auth登录。
任何建议将不胜感激。
