Slider.label documentation should be clearer about behavior with continuous sliders #74098
Description
The documentation for Slider.label says:
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.
While it says that the label is used with discrete sliders, it doesn't actually say anything about continuous sliders. The implication from omission is that labels won't be shown for continuous sliders (which I verified is the case), but it would be much clearer to explicitly say so, in the same way that the documentation later says:
Ignored if this slider is created with Slider.adaptive.
Also, why is the label limited only to discrete sliders anyway?

Okay, looking at the code, I see that by default, the label is shown only for discrete sliders, but labels can be enabled for continuous sliders by setting
SliderThemeData.showValueIndicatorin a parentSliderThemewidget.Showing labels only for discrete sliders still seems like a weird default, and the documentation still should be updated to mention
