}) {
  final coreName = _CString(name);

  final coreData = data.toByteArrayWrapper();
  final taskHandle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_ArcGISFeature_addAttachment(
      _handle,
      coreName.bytes,
      coreContentType.bytes,
      coreData.ref,
      errorHandler,
