Does anyone know where to find the documentation? I saw several components using this library, but strangely could not find the documentation?
Facebook's answer to this question https://github.com/facebook/react-native/issues/4789 is that the library is good for production, but unfortunately there is no documentation for it :(
React Native ART is the RN version of React ART, which in itself is an implementation of the ART library. And the latter has several documents:

They are not exhaustive, but they should be enough to get you started.
