Interval class Null safety
A curve that is 0.0 until begin, then curved (according to curve) from 0.0 at begin to 1.0 at end, then remains 1.0 past end.
An Interval can be used to delay an animation. For example, a six second animation that uses an Interval with its begin set to 0.5 and its end set to 1.0 will essentially become a three-second animation that starts three seconds later.
