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.
