SliderComponentShape class

Base class for slider thumb, thumb overlay, and value indicator shapes.

Create a subclass of this if you would like a custom shape.

All shapes are painted to the same canvas and ordering is important. The overlay is painted first, then the value indicator, then the thumb.

The thumb painting can be skipped by specifying noThumb for SliderThemeData.thumbShape.

The overlay painting can be skipped by specifying noOverlay for SliderThemeData.overlayShape.
