SliderTheme class Null safety
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.
The slider is as big as the largest of the SliderComponentShape.getPreferredSize of the thumb shape, the SliderComponentShape.getPreferredSize of the overlay shape, and the SliderTickMarkShape.getPreferredSize of the tick mark shape.
