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({
    'heightFactor': heightFactor,
    'widthFactor': widthFactor,
    'child': child?.toJson(),
    ...args,
  });
}
