StacRadio class

A Stac model representing Flutter's Radio and CupertinoRadio widgets.

Displays a circular selection control that allows the user to select one option from a set. The radioType controls whether a Material, Cupertino, or adaptive variant is rendered by the parser.

{@tool snippet} Dart Example:

StacRadio(
  radioType: StacRadioType.material,
  value: 'a',
  groupId: 'letter',
  activeColor: StacColors.blue,
)

{@end-tool}

{@tool snippet} JSON Example:

{
  "type": "radio",
  "radioType": "material",
  "value": "a",
  "groupId": "letter",
  "activeColor": "#2196F3"
}

{@end-tool}
