toJson method

@override dynamic toJson()

toJson returns a json compatible object.

Descendants must override this method to expose custom properties.

Implementation

@override
toJson() {
  return super.toJson()
    ..addAll(<String, dynamic>{
      'padding': padding.toJson(),
      'duration': duration.toJson(),
      'curve': curve.toJson(),
      if (child != null) 'child': child!.toJson(),
    });
}
