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({
    'alignment': Alignment.center == alignment
        ? null
        : ThemeEncoder.encodeAlignmentGeometry(
            alignment,
          ),
    'clipBehavior': Clip.none == clipBehavior
        ? null
        : ThemeEncoder.encodeClip(
            clipBehavior,
          ),
    'fit': BoxFit.contain == fit
        ? null
        : ThemeEncoder.encodeBoxFit(
            fit,
          ),
    'child': child?.toJson(),
    ...args,
  });
}
