writeHealthData method

Future<bool> writeHealthData(double value, HealthDataType type, DateTime startTime, DateTime endTime, { HealthDataUnit? unit, })

Saves health data into Apple Health or Google Fit.

Returns true if successful, false otherwise.

Parameters:

• value - the health data's value in double
• type - the value's HealthDataType
• startTime - the start time when this value is measured.
  • It must be equal to or earlier than endTime.
• endTime - the end time when this value is measured.
  • It must be equal to or later than startTime.
  • Simply set endTime equal to startTime if the value is measured only at a specific point in time.
• unit - (iOS ONLY) the unit the health data is measured in.

Values for Sleep and Headache are ignored and will be automatically assigned the coresponding value.

Implementation

Future<bool> writeHealthData(
  double value,
  HealthDataType type,
  DateTime startTime,
  DateTime endTime, {
  HealthDataUnit? unit,
}) async {
  if (type == HealthDataType.WORKOUT)
    throw ArgumentError(
        "Adding workouts should be done using the writeWorkoutData method.");
  if (startTime.isAfter(endTime))
    throw ArgumentError("startTime must be equal or earlier than endTime");
  if ({
        HealthDataType.HIGH_HEART_RATE_EVENT,
        HealthDataType.LOW_HEART_RATE_EVENT,
        HealthDataType.IRREGULAR_HEART_RATE_EVENT,
        HealthDataType.ELECTROCARDIOGRAM,
      }.contains(type) &&
      _platformType == PlatformType.IOS)
    throw ArgumentError(
        "$type - iOS doesnt support writing this data type in HealthKit");

  // Assign default unit if not specified
  unit ??= _dataTypeToUnit[type]!;

  // Align values to type in cases where the type defines the value.
  // E.g. SLEEP_IN_BED should have value 0
  if (type == HealthDataType.SLEEP_ASLEEP ||
      type == HealthDataType.SLEEP_AWAKE ||
      type == HealthDataType.SLEEP_IN_BED ||
      type == HealthDataType.HEADACHE_NOT_PRESENT ||
      type == HealthDataType.HEADACHE_MILD ||
      type == HealthDataType.HEADACHE_MODERATE ||
      type == HealthDataType.HEADACHE_SEVERE ||
      type == HealthDataType.HEADACHE_UNSPECIFIED) {
    value = _alignValue(type).toDouble();
  }
