PrismSlider class

A slider styled with Prism tokens and accessible to screen readers.

Wraps Flutter's Slider and adds a Semantics label, a value display and a haptic response, so it is usable without sight and gives feedback you can feel.

PrismSlider(
  value: volume,
  min: 0,
  max: 100,
  label: 'Volume',
  onChanged: (v) => setVolume(v),
