Implementation

Map<String, dynamic> toJson() {
  Map<String, dynamic> json = {
    "RootNode": getRootNode().toJson(),
    "Zoom": getZoom().toString(),
    "BackgroundColor": colorToString(getBackgroundColor()),
  };
  if (getOffset() != null) {
    json["x"] = getOffset()!.dx.toString();
    json["y"] = getOffset()!.dy.toString();
  }
  return json;
