RangeSliderTrackShape class Null safety

Base class for RangeSlider track shapes.

The slider's thumbs move along the track. A discrete slider's tick marks are drawn after the track, but before the thumb, and are aligned with the track.

The getPreferredRect helps position the slider thumbs and tick marks relative to the track.
