var _listHorizontal = ["Horizontal 1", "Horizontal 2", "Horizontal 3"];
var _indexHorizontal = 0;

FlutterRadioGroup(
                 titles: _listHorizontal,
                 labelStyle: TextStyle(color: Colors.white38),
                 labelVisible: true,
                 label: "This is label radio",
                 activeColor: Colors.blue,
                 titleStyle: TextStyle(fontSize: 14),
                 defaultSelected: _indexHorizontal,
                 orientation: RGOrientation.HORIZONTAL,
                 onChanged: (index) {
                   setState(() {
                     _indexHorizontal = index;
                   });
                 }),

Select Index Programmatically

var _key = GlobalKey<RadioGroupState>();

/// Update selected radio
_key.currentState.setIndexSelected(3);

FlutterRadioGroup(
		  key:_key
                  titles: _listHorizontal,
