One of the downsides to working with React Native is that react native provides access to only a small fraction of the APIs available on iOS and Android forcing developers to create native wrappers for missing APIs.
Tal Kol of Wix has created a great library to help remedy this utilizing reflection to allow you to access all native APIs with a clean and simple syntax. Tal created this because he wanted to access the contentOffset method which is not provided with React Native’s scroll view implementation.
