RoundSliderTickMarkShape class

The default shape of each Slider tick mark.

Tick marks are only displayed if the slider is discrete, which can be done by setting the Slider.divisions to an integer value.

It paints a solid circle, centered in the on the track. The color is determined by the Slider's enabled state and track's active states. These colors are defined in: SliderThemeData.activeTrackColor, SliderThemeData.inactiveTrackColor, SliderThemeData.disabledActiveTrackColor, SliderThemeData.disabledInactiveTrackColor.
