Describe the bug

There appears to be a mismatch of argument names between Flutter bridge and Kotlin code:

Compare health_plugin.dart:

  Future<List<HealthDataPoint>> _dataAggregateQuery(
      DateTime startDate,
      DateTime endDate,
      List<HealthDataType> dataTypes,
      int activitySegmentDuration,
      bool includeManualEntry) async {
    final args = <String, dynamic>{
      'dataTypeKeys': dataTypes.map((dataType) => dataType.name).toList(),
      'startTime': startDate.millisecondsSinceEpoch,
      'endTime': endDate.millisecondsSinceEpoch,
      'activitySegmentDuration': activitySegmentDuration,
      'includeManualEntry': includeManualEntry
    };

    final fetchedDataPoints =
        await _channel.invokeMethod('getAggregateData', args);

compare with Kotlin implementation:

        val dataType = call.argument<String>("dataTypeKey")!!
        val interval = call.argument<Long>("interval")!!
        val startTime = Instant.ofEpochMilli(call.argument<Long>("startTime")!!)
        val endTime = Instant.ofEpochMilli(call.argument<Long>("endTime")!!)

And note the difference in parameter names for dataTypeKey vs dataTypeKeys and also for interval vs activitySegmentDuration.

Steps to Reproduce

Calling getHealthAggregateDataFromTypes with AndroidHealthConnect raises java.lang.NullPointerException.

var aggregatedResult = await Health().getHealthAggregateDataFromTypes(
        types: [ HealthDataType.STEPS ],
        startDate: from,
        endDate: till,
        includeManualEntry: false,
        activitySegmentDuration: 3600,
      );

Expected Behavior

Return data aggregated in buckets of specified interval.

Actual Behavior

Throwing java.lang.NullPointerException

I have same issue.
My code:

final endTime = DateTime.now();
final startTime = endTime.copyWith(hour: 0, minute: 0, second: 0);
final result = await Health().getHealthAggregateDataFromTypes(
        types: types,
        startDate: startTime,
        endDate: endTime,
      );

My types and permissions:

final types = [
    // HealthDataType.DISTANCE_WALKING_RUNNING,
    HealthDataType.ACTIVE_ENERGY_BURNED,
    HealthDataType.STEPS,
  ];

  List<HealthDataAccess> get permissions =>
      types.map((type) => HealthDataAccess.READ_WRITE).toList();

My log:

On iOS, it does not even throw any exception.
Nothing happens on iOS.

SAME PROBLEM, is there a fix to it?

It seems that getAggregateData function is only implemented for Android, but not for iOS. Is there a timeline when this would be implemented?
