Constructors

RotaryScrollbar({Key? key, required ScrollController controller, required Widget child, double padding = 8, double width = 8, bool autoHide = true, Curve opacityAnimationCurve = Curves.easeInOut, Duration opacityAnimationDuration = const Duration(milliseconds: 250), Duration autoHideDuration = const Duration(seconds: 3), bool hasHapticFeedback = true, Duration pageTransitionDuration = const Duration(milliseconds: 250), Curve pageTransitionCurve = Curves.easeInOutCirc, double scrollMagnitude = 50, Duration scrollAnimationDuration = const Duration(milliseconds: 100), Curve scrollAnimationCurve = Curves.linear})
A scrollbar which curves around circular screens and reacts to Rotary events. Similar to native wearOS scrollbar in devices with round screens.
