The default is to use a continuous range of values from min to max.

listeners : onChanged, onChangeStart, onChangeEnd

 //in a statefull widget

 double seekValue = 0;

 Widget _buildSlider() {
   return Row(
     children: <Widget>[

       Flexible(
         child: EmergentSlider(
             height: 15,
             value: seekValue,
             min: 0,
             max: 10,
             onChanged: (value) {
               setState(() {
                 seekValue = value;
               });
