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({
    'fit': FlexFit.loose == fit
        ? null
        : ThemeEncoder.encodeFlexFit(
            fit,
          ),
    'flex': 1 == flex ? null : flex,
    'child': child.toJson(),
    ...args,
  });
}
