label property
A label to show above the slider when the slider is active.
It is used to display the value of a discrete slider, and it is displayed as part of the value indicator shape.
The label is rendered using the active ThemeData's
ThemeData.textTheme.bodyText1 text style, with the
theme data's ThemeData.colorScheme.onPrimaryColor. The label's text style
can be overridden with SliderThemeData.valueIndicatorTextStyle.
If null, then the value indicator will not be displayed.
Ignored if this slider is created with Slider.adaptive.
