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({
    'maxHeight': double.infinity == maxHeight ? null : maxHeight,
    'maxWidth': double.infinity == maxWidth ? null : maxWidth,
    'child': child?.toJson(),
    ...args,
  });
}
