WheelMotion class sealed

How a SmoothScrollController moves to its wheel target.

WheelMotion.spring and WheelMotion.lerp follow a moving target, so wheel input during the motion changes where it goes without starting over. WheelMotion.curve starts a new curve from the current position on every wheel input.

Constructors

WheelMotion.curve({Duration duration, Curve curve})

A curve over duration, restarted from the current position on every wheel input.

const

factory

WheelMotion.lerp({Duration timeConstant})

Covers a fixed fraction of the remaining distance per unit of time: after timeConstant, about 63% of it.

const

factory

WheelMotion.spring({Duration duration, double bounce})

A critically damped spring when bounce is 0, which arrives as fast as possible without passing the target.
