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 TextTheme.bodyText1
text style, with the theme data's ColorScheme.onPrimary color. 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 IntervalSlider.adaptive.
