How can I implement persistent storage in React Navigation?

You can use libraries like AsyncStorage or SecureStore to save navigation state. Would you like a code example?

Yes, please provide a code example using AsyncStorage.

Sure! First, install AsyncStorage: npm install @react-native-async-storage/async-storage. Then, you can save the navigation state like this:

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
  }
};

Would you like to know how to retrieve the state?

Yes, how do I retrieve the saved navigation state?

To retrieve the saved navigation state, you can use the following code:

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

This will give you the saved state when you need it.
