buildCustom method

@override Widget buildCustom({ ChildWidgetBuilder? childBuilder, required BuildContext context, required JsonWidgetData data, Key? key, })

Builds the widget to render to the tree. If enabled property is true then this will attach the selected value to the JsonWidgetRegistry using the id as the key any time the selected value is changed.

Likewise, this will set any error messages using the key '$id.error'. An empty string will be used to represent no error message.

The id value must be the same for all radios in the group and each radio will listen to the JsonWidgetRegistry for value updates to be able to properly select / de-select.

Implementation

@override
Widget buildCustom({
  ChildWidgetBuilder? childBuilder,
  required BuildContext context,
  required JsonWidgetData data,
  Key? key,
}) {
  final child = getChild(data);

  return _JsonRadioWidget(
    builder: this,
    childBuilder: childBuilder,
    data: data,
    key: key,
    child: child,
  );
}
