Warning: Animated: `useNativeDriver` was not specified. This is a required option and must be explicitly set to `true` or `false`

This is a new warning in React 0.62.0:

Make setting useNativeDriver required. Add runtime warning if not specified (5876052615 by @TheSavior)

The background is here: https://reactnative.dev/blog/2017/02/14/using-native-driver-for-animated/

However, that notes:

Not everything you can do with Animated is currently supported in Native Animated. The main limitation is that you can only animate non-layout properties, things like transform and opacity will work but Flexbox and position properties won't.

Here is an example stack of the react-native-amazing-cropper warning:

Since Cropper is using Animated on a position property, I think useNativeDriver should be set to false.

@3GOMESz I don't think that's fair. He recently implemented something for me and is relatively responsive for a free project. I do hope to find time to prototype the changes for the issue but it's not as easy as just a PR: it requires testing, etc.

What do you mean "fair"? I just want to say that this kind of problem is solved with literally one line of code and the last update on the project was 5 months ago.
