Specifies the radius for the overlay in the SfSlider, SfRangeSlider, and SfRangeSelector.

Overlay appears while interacting with thumbs.

This snippet shows how to set overlay radius in SfRangeSliderThemeData.

SfRangeValues _values = SfRangeValues(4.0, 8.0);

Scaffold(
    body: Center(
        child: SfRangeSliderTheme(
            data: SfRangeSliderThemeData(
                overlayRadius: 22,
            ),
            child:  SfRangeSlider(
                min: 2.0,
                max: 10.0,
                values: _values,
                onChanged: (SfRangeValues newValues){
                    setState(() {
                        _values = newValues;
                    });
                },
           )
       ),
   )
