## Implementation

    Polygon copyWith({
      List<LatLng> pointsParam,
      double strokeWidthParam,
      Color strokeColorParam,
      Color fillColorParam,
      bool visibleParam,
    }) {
      Polygon copyPolyline = Polygon(
        points: pointsParam ?? points,
        strokeWidth: strokeWidthParam ?? strokeWidth,
        strokeColor: strokeColorParam ?? strokeColor,
        fillColor: fillColorParam ?? fillColor,
        visible: visibleParam ?? visible,
        joinType: joinType,
      );
      copyPolyline.setIdForCopy(id);
      return copyPolyline;
    }
