getData method

  1. @override
Future<List<HealthKitData>> getData(
  1. List<HealthKitHealthMetric> metrics,
  2. DateTimeRange<DateTime> timeRange
)
override

Retrieves health data for specified metrics within the given time range. Returns a list of typed health data objects (heart rate, body temperature, etc.).

Implementation

@override
Future<List<HealthKitData>> getData(
  List<HealthKitHealthMetric> metrics,
  DateTimeRange timeRange,
) async {
  final start = timeRange.start.toUtc().toIso8601String();
  final end = timeRange.end.toUtc().toIso8601String();
  List<String> types = [];
  for (final metric in metrics) {
    types.add(metric.definition);
  }

  Map<String, List<dynamic>>? response = await methodChannel.invokeMapMethod(
    "$healthKitPrefix/$getDataSuffix",
    {"start": start, "end": end, "types": types},
  );

  if (response == null) {
    throw Exception("[HealthKit] getData returned null");
  }

  List<HealthKitData> result = _convertToHealthKitData(response);
  return result;
}
