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 couple 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, similar to createNativeStackNavigator. This is a popular alternative to React Navigation and may be a better fit for you if you are trying to integrate React Native into an existing large native app.
