[health 10.1.1] Health.hasPermissions don't works propely

[ifuterman]

iOS emulator version 17.2

Emulator

Please complete the following information for each phone and/or emulator you're experiencing this bug on:

• Device: [iPhone 15 Pro]
• OS: [iOS 17.2]

Describe the bug

Regardless of the outcome, the result of the execution is always null

To Reproduce

1. I manually add the steps with the health app
2. Start app. In the popup, I restricted access to the health data. The result of the Health().requestAuthorization will be true, and the result of the Health().hasPermissions will be null. The x will be the empty list
3. Open settings->Health grant access to all data
4. Start app. The result of the Health().requestAuthorization will be true, and the result of all Health().hasPermissions will be null. The x will be the list with one element

const dataTypesIOS = <HealthTypeAndPermission>[
  HealthTypeAndPermission(healthType: HealthDataType.SLEEP_ASLEEP, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.STEPS, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.HEART_RATE, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.HEART_RATE_VARIABILITY_SDNN, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.RESTING_HEART_RATE, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.FORCED_EXPIRATORY_VOLUME, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.RESPIRATORY_RATE, access: HealthDataAccess.READ),
  HealthTypeAndPermission(healthType: HealthDataType.EXERCISE_TIME, access: HealthDataAccess.READ),
];

List<HealthTypeAndPermission> get dataTypes => Platform.isIOS ? dataTypesIOS : dataTypesAndroid;

Future<bool> authorize() async{
    _isInited = false;
    try{
      bool? permissions = await health.hasPermissions(
        dataTypes.map((e) => e.healthType).toList(),
        permissions: dataTypes.map((e) => e.access).toList()
      );
      if(permissions != null && permissions){
        _isInited = true;
        return true;
      }
      if(permissions == null || !permissions){
        _isInited = await health.requestAuthorization(
            dataTypes.map((e) => e.healthType).toList(),
            permissions: dataTypes.map((e) => e.access).toList()
        );
        //_isInited will be true always
        for(final dataType in dataTypes){
          final result = await health.hasPermissions([dataType.healthType], permissions: [dataType.access]);
          debugPrint('HealthService.authorise $result');
        }
        permissions = await health.hasPermissions(
            dataTypes.map((e) => e.healthType).toList(),
            permissions: dataTypes.map((e) => e.access).toList()
        );
        _isInited = permissions != null ? _isInited : false;
        final x = await health.getHealthDataFromTypes(DateTime.now().subtract(Duration(days: 20)), DateTime.now(), dataTypes.map((e) => e.healthType).toList());
        return _isInited ? true : false;
      }

    }catch (error){
      debugPrint('HealthWrapper.authorise EXCEPTION: ${error.toString()}');
    }
    return false;
  }

Expected behavior

If I have access to the parameter the result of the Health().hasPermissions needs to be not null; the result of the Health().requestAuthorization should depend on the request result.

Actual behavior

The result of the Health().hasPermissions is always null, even if I check specific allowed parameters with read access.
And I can read this parameter. Health().requestAuthorization always true

I have the same problem. Did you manage to fix it?

No. I downgraded to 9.0.0. For some reason, this version works, but the last doesn`t. I want to show popup, if the data reading restricted for me, because the iOS don't show embedded popup after the first time

Any fix?

hey there,
In the documentation for the method hasPermissions you can read the following.

"As Apple HealthKit will not disclose if READ access has been granted for a data type due to privacy concern, this method can only return null to represent an undetermined status, if it is called on iOS with a READ or READ_WRITE access."
