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() => JsonClass.removeNull({
      'type': type,
      'id': id,
      'args': args,
      'children': JsonClass.toJsonList(children),
    });
