Screen tracking for analytics

To track the currently active screen, we need to:

Add a callback to get notified of state changes
Get the root navigator state and find the active route name

To get notified of state changes, we can use the onStateChange prop on NavigationContainer. To get the root navigator state, we can use the getRootState method on the container's ref. Please note that onStateChange is not called on initial render so you have to set your initial screen separately.

Example

This example shows how the approach can be adapted to any mobile analytics SDK.

Static
Dynamic

import { View } from 'react-native';

function Home() {
  const navigation = useNavigation();

  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Button onPress={() => navigation.navigate('Settings')}>
        Go to Settings
      </Button>
