Get coordinate of element

[DanielMSchmidt]

Hi there,

Thanks again for this awesome piece of code!

I would like to test if a selected element has certain absolute x and y coordinates. A matcher for this would be cool, but I can't figure out how to do it. Can you point me in the right direction, so that I may do a PR?

You know, I don't think this is a good API. It assumes a lot on the layout system of both iOS and RN, which is not good practice.
