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({
