RoundedRectRangeSliderTrackShape class
The default shape of a RangeSlider's track.
It paints a solid colored rectangle with rounded edges, vertically centered
in the parentBox. The track rectangle extends to the bounds of the
parentBox, but is padded by the larger of RoundSliderOverlayShape's
radius and RoundRangeSliderThumbShape's radius. The height is defined by
the SliderThemeData.trackHeight. The color is determined by the
RangeSlider'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.
