How do you handle offline functionality in a React Native app?

Handling offline functionality involves: 

• Data Storage: Use libraries like Redux Persist or AsyncStorage to store data locally. 
• Synchronization: Sync local data with the server when the connection is restored. 
• Fallback UI: Provide fallback UI elements to inform users about the offline status. 

These techniques ensure the app remains functional and provides a smooth user experience even without an internet connection.
