Access the Google Fitness API (Sleep Data ) Flutter Firebase login using Facebook Auth?

Question

We are building a Mobile app using Flutter that reads the Sleep Data and shows a dashboard based on the Sleep Data,

We are using Firebase for Social Login. Currently we support Google, Facebook and Custom Email / Password based login.

Google Sign-in

The app is getting Sleep Data, when the user logins using Google Account. We are passing the Google API scope as shown below.

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

Facebook Sign-in

If the user logins using Facebook Account, we are getting the below error. Not sure, how to pass Google API scope in Facebook Login. I am getting the below issue:

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!

W/FLUTTER_HEALTH::ERROR(31643): [Ljava.lang.StackTraceElement;@abd9db8

Please take a look at the code we are using:

`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));
    }
  }`

Please help me to read Sleep Data from Google API using Flutter Firebase. The User is logged in using Facebook Auth.

Any advice would be appreciated.

Google services cannot be accessed with a Facebook auth. Google auth is required for this purpose. Use Google Auth as your primary sign-in method, and use Facebook Auth only if necessary for what purpose you need it for.
