SliderTheme class
Applies a slider theme to descendant Slider widgets.
A slider theme describes the colors and shape choices of the slider components.
Descendant widgets obtain the current theme's SliderThemeData object using SliderTheme.of. When a widget uses SliderTheme.of, it is automatically rebuilt if the theme later changes.

- SliderThemeData, which describes the actual configuration of a slider theme.
