Describe the bug
When I'm canceling animate function with width and height parameters, app crash on only android platform. Error is "android.view.View.getLayoutParams() on a null object reference".

If I set a scale parameter, it works properly.

To Reproduce
Open the following playground project
Run app
Tap the "Start" button.

Expected behavior
I can stop the animation.
