CupertinoRangeSlider class
An iOS-style 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.
