double _lowerValue = 0.0;
double _upperValue = 400.0;
frs.RangeSlider(

                          min: 0.0,
                          max: 400.0,
                          lowerValue: _lowerValue,
                          upperValue: _upperValue,
                          divisions: _upperValue.toInt(),
                          showValueIndicator: true,
                          valueIndicatorMaxDecimals: 1,

                            setState(() {
                              _upperValue = newUpperValue;
