Curve class

Describes the timing function of a transition.

This defines an acceleration curve so that the speed of the transition can vary over its duration.

Constructors

Curve.cubicBezier(double p1, double p2, double p3, double p4)

An custom cubic-Bezier curve, where the p1 and p3 values must be in the range of 0 to 1.

Curve.steps(int steps, {required StepJump jump})

Displays the transition along steps stops along the transition, displaying each stop for equal lengths of time. How the transition behaves at the start and end is defined by jump.

Constants

ease → const Curve

Equal to cubic-bezier(0.25, 0.1, 0.25, 1.0), the default value, increases in velocity towards the middle of the transition, slowing back down at the end.

easeIn → const Curve

Equal to cubic-bezier(0.42, 0, 1.0, 1.0), starts off slowly, with the transition speed increasing until complete.

easeInOut → const Curve

Equal to cubic-bezier(0.42, 0, 0.58, 1.0), starts transitioning slowly, speeds up, and then slows down again.

easeOut → const Curve

Equal to cubic-bezier(0, 0, 0.58, 1.0), starts transitioning quickly, slowing down as the transition continues.

linear → const Curve

Equal to cubic-bezier(0.0, 0.0, 1.0, 1.0), transitions at an even speed.

stepEnd → const Curve

Equal to steps(1, jump-end).

stepStart → const Curve

Equal to steps(1, jump-start).
