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

                            setState(() {
                              _upperValue = newUpperValue;
                            });
                          },
                          onChangeStart: (double startLowerValue,
