[Feature Request] Disable animations globally

[xavierLowmiller]

Description

In our app, we do a lot of snapshot testing. To keep these deterministic, we disable the Lottie animations by hand, which works :+1:.

It would be much easier, though, if Lottie looked at UIView.areAnimationsEnabled so that animations could be enabled or disabled globally.

@xavierLowmiller how do you disable the animations while you take the snapshots?

[xavierLowmiller]

Just set UIView.setAnimationsEnabled(false)

@xavierLowmiller ah ok! Do you know how to display only the final frame so that the test don’t have to wait for the animation to finish ?

Oh sorry, you mean how we disable the Lottie animations?

I can't take a look how we exactly did it because I've switched jobs and don't have access to the code base.

As far as I remember, we just called stop() on the view, and maybe set the animationProgress to some deterministic value.
