IntTween class Null safety

An interpolation between two integers that rounds.

This class specializes the interpolation of Tween<int> to be appropriate for integers by interpolating between the given begin and end values and then rounding the result to the nearest integer.

This is the closest approximation to a linear tween that is possible with an integer. Compare to StepTween and Tween<double>.

The begin and end values must be set to non-null values before calling lerp or transform.

See Tween for a discussion on how to use interpolation objects.

animate(Animation<double> parent) Animation<int>
Returns a new Animation that is driven by the given animation but that takes on values determined by this object. [...]
chain(Animatable<double> parent) Animatable<int>
Returns a new Animatable whose value is determined by first evaluating the given parent and then evaluating this object. [...]
evaluate(Animation<double> animation) int
The current value of this object for the given Animation. [...]
lerp(double t) int
Returns the value this variable has at the given animation clock value. [...]
