React Navigation isn't your only option for routing and navigation in React Native. If the pitch & anti-pitch or the API design leave you wanting to explore other options, here are a few to consider.
- react-native-router-flux: this library is based on React Navigation but provides you with a different API to interact with it.
- react-native-navigation: uses the underlying native APIs on iOS and Android, this is a popular alternative to React Navigation and worth considering if you value adhering to the platform conventions exactly and do not care as much about customization.
- react-router-native: this library is somewhat incomplete, but if you're familiar with the React Router API already and have simple requirements for your app, this might work for you.
