One thing to add... saying "just use react-native-navigation" is not always the greatest advice. Yes, it may be technically more performant, but my god does it cause a wealth of issues. Unless you have real experience of different routing libraries, don't make the mistake I did and assume it would be a wonderful easy process. RNN treats all screens of your app as an individual sandboxed thread and so they can't communicate with each other; this can make things very complex very fast, especially maintaining state
