This is the start of my effort to document and follow up with examples everything that was worked on in the last 6 months . https://twitter.com/mihaelkonjevic/status/988138489664491522
I would recommend you to check out https://github.com/keechma/example-keechma-react-native/blob/master/src/example_rn/components/router.cljs which does some cool things that are impossible with other frameworks.

It also has a pretty extensive example of how animations work
