How can I implement data persistence in React Navigation?

How can I implement data persistence in React Navigation?

You can use AsyncStorage to save navigation state and restore it when the app restarts.

Can you show me a code example?

Sure! Here's a simple example:

import AsyncStorage from '@react-native-async-storage/async-storage';

const saveNavigationState = async (state) => {
  try {
    await AsyncStorage.setItem('@navigation_state', JSON.stringify(state));
  } catch (e) {
    // saving error
  }
};

const loadNavigationState = async () => {
  try {
    const jsonValue = await AsyncStorage.getItem('@navigation_state');
    return jsonValue != null ? JSON.parse(jsonValue) : null;
  } catch (e) {
    // error reading value
  }
};

This code saves and loads the navigation state.

What about handling deep links?

For deep linking, you can use the linking prop in your navigator to handle incoming URLs.

Are there any libraries that can help with this?

Yes, libraries like react-navigation and @react-native-async-storage/async-storage are great for managing navigation and data persistence.
