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.

See also:

  • SliderThemeData, which describes the actual configuration of a slider theme.
  • SliderComponentShape, which can be used to create custom shapes for the slider thumb and value indicator.
