    }
  }

  addIfPresent('heatmapId', heatmapId.value);
  addIfPresent('data', data.map((WeightedLatLng e) => e.toJson()).toList());
  addIfPresent('dissipating', dissipating);
  addIfPresent('gradient', gradient?.toJson());
  addIfPresent('maxIntensity', maxIntensity);
  addIfPresent('opacity', opacity);

  addIfPresent('minimumZoomIntensity', minimumZoomIntensity);
  addIfPresent('maximumZoomIntensity', maximumZoomIntensity);
