RoundedRectSliderTrackShape class

The default shape of a Slider'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 RoundSliderThumbShape's 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 start of the slider and the thumb is the active track segment. The track segment between the thumb and the end of the slider is the inactive track segment. 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.
