property
animationFrame

Future<num> animationFrame
read-only

Returns a Future that completes just before the window is about to repaint so the user can draw an animation frame.

If you need to later cancel this animation, use [requestAnimationFrame] instead.

The [Future] completes to a timestamp that represents a floating point value of the number of milliseconds that have elapsed since the page started to load (which is also the timestamp at this call to animationFrame).

Note: The code that runs when the future completes should call [animationFrame] again for the animation to continue.
