I've not tested it myself, but this came in through another customer.

Here is the example:

There also is likely a bug in either my integration code or the original sample as it does not redraw correctly while animating. If you hit the "p" key in flutter run (or any other key which forces a redraw) you can see it's actually animating, just not redrawing.

@HansMuller might see the redraw bug off the top of his head.

@chinmaygarde volunteered to take a look at the perf.
