HandleRangeSliderThumbShape class
The bar shape of RangeSlider's thumbs.
When the range 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.
If ThemeData.useMaterial3 is true and RangeSlider.year2023 is false, then the RangeSlider will use HandleRangeSliderThumbShape as the default track shape.
