RectangularRangeSliderTrackShape class
A RangeSlider track that's a simple rectangle.
It paints a solid colored rectangle, vertically centered in the
parentBox. The track rectangle extends to the bounds of the parentBox,
but is padded by the RoundSliderOverlayShape radius. The height is
defined by the SliderThemeData.trackHeight. The color is determined by the
Slider's enabled state and the track segment's active state which are
defined by:
SliderThemeData.activeTrackColor,
SliderThemeData.inactiveTrackColor,
SliderThemeData.disabledActiveTrackColor,
SliderThemeData.disabledInactiveTrackColor.
The track segment between the two thumbs is the active track segment. The track segments between the thumb and each end of the slider are the inactive track segments. In TextDirection.ltr, the start of the slider is on the left, and in TextDirection.rtl, the start of the slider is on the right.
