A material design slider.
Used to select from a range of values.
A slider can be used to select from either a continuous or a discrete set of values. The default is use a continuous range of values from min to max. To use discrete values, use a non-null value for divisions, which indicates the number of discrete intervals. For example, if min is 0.0 and max is 50.0 and divisions is 5, then the slider can take on the values discrete values 0.0, 10.0, 20.0, 30.0, 40.0, and 50.0.
The slider itself does not maintain any state. Instead, when the state of the slider changes, the widget calls the onChanged callback. Most widgets that use a slider will listen for the onChanged callback and rebuild the slider with a new value to update the visual appearance of the slider.
Requires one of its ancestors to be a Material widget.
