toJson method

@override Map<String, dynamic> toJson()

Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.

While not required, it is suggested to call removeNull before returning.

Implementation

@override
Map<String, dynamic> toJson() {
  return JsonClass.removeNull({
    'bottom': bottom,
    'height': height,
    'left': left,
    'right': right,
    'top': top,
    'width': width,
    'child': child.toJson(),
    ...args,
  });
}
