This snippet shows how to set thumb color in SfRangeSliderThemeData.

SfRangeValues _values = SfRangeValues(4.0, 8.0);

Scaffold(
    body: Center(
        child: SfRangeSliderTheme(
            data: SfRangeSliderThemeData(
                thumbColor: Colors.red,
            ),
            child:  SfRangeSlider(
                min: 2.0,
                max: 10.0,
                values: _values,
                interval: 1,
                showTicks: true,
                showLabels: true,
                onChanged: (SfRangeValues newValues){
                    setState(() {
                        _values = newValues;
                    });
                },
