buildCustom({ChildWidgetBuilder? childBuilder, required BuildContext context, required JsonWidgetData data, Key? key}) → Widget
Custom builder that subclasses must override and implement to return the actual Widget to be placed on the tree.
createModel({ChildWidgetBuilder? childBuilder, required JsonWidgetData data}) → JsonWidgetBuilderModel
noSuchMethod(Invocation invocation) → dynamic
