toJson method

Implementation

@override
Map<String, dynamic> toJson() {
  final Map<String, dynamic> json = <String, dynamic>{};
  if (offsetX != null) {
    json['offsetX'] = offsetX;
  }
  if (offsetY != null) {
    json['offsetY'] = offsetY;
  }
  if (x != null) {
    json['x'] = x;
  }
  if (y != null) {
    json['y'] = y;
  }
  return json;
}
