When is native driver used?

[H-Shafiei]

Hi,

Thanks for the awesome library! I did not understand how the native driver is used? If I have an image as a shared element, on which conditions does this library use native drivers?
More specifically, if I use width and height in style would this image transition use native driver or not? For example, the FlatList example.

Thanks

It uses native driver by default and as stated in this React native blog post:

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.

Not sure if it can be disabled since I dont see any problems "yet" with animations on JS thread, but that will open up a lot of animation possibilities.
