NyFormRangeSlider class

A range slider widget for forms that allows users to select a range of values.

NyFormRangeSlider provides a Material Design range slider interface where users can select a range by dragging two thumbs along a track. The widget displays the current range values and allows customization of min/max values, divisions, and styling.

Example usage:

NyFormRangeSlider(
  name: 'price_range',
  values: RangeValues(10.0, 90.0),
  min: 0.0,
  max: 100.0,
  divisions: 10,
  onChanged: (values) => print('Range: ${values.start} - ${values.end}'),
)
