AnnotatedHandleThumbShape class

The bar shape of a Slider's thumb.

When the slider is enabled, the ColorScheme.primary color is used for the thumb. When the slider is disabled, the ColorScheme.onSurface color with an opacity of 0.38 is used for the thumb.

The thumb bar shape width is reduced when the thumb is pressed.

If SliderThemeData.thumbSize is null, then the thumb size is 4 pixels for the width and 44 pixels for the height.

This is the default thumb shape for Slider. If ThemeData.useMaterial3 is false, then the default thumb shape is RoundSliderThumbShape.
