GappedRangeSliderTrackShape class

The GappedRangeSliderTrackShape consists of active and inactive tracks. The active track uses the SliderThemeData.activeTrackColor and the inactive tracks uses the SliderThemeData.inactiveTrackColor.

The track shape uses circular corner radius for the edge corners and a corner radius of 2 pixels for the inside corners.

Between the active and inactive tracks there are gaps of size SliderThemeData.trackGap. If the SliderThemeData.thumbShape is HandleRangeSliderThumbShape and the thumb is pressed, the thumb's width is reduced; as a result, the track gaps size in GappedRangeSliderTrackShape is also reduced.

If SliderThemeData.trackGap is null, then the track gaps size defaults to 6 pixels.

If ThemeData.useMaterial3 is true and RangeSlider.year2023 is false, then the RangeSlider will use GappedRangeSliderTrackShape as the default track shape.

  • RangeSlider, which includes a track defined by this shape.
  • SliderTheme, which can be used to configure the track shape of all range sliders in a widget subtree.
