For a Flutter app that needs to sync local files with a cloud server, what considerations must be taken into account for efficient and secure data handling?

When syncing local files with a cloud server in a Flutter app, several considerations must be taken into account for efficient and secure data handling. Using secure protocols such as HTTPS ensures encrypted and secure data transmission. Implementing encryption for data transmission adds an extra layer of security. Validating and sanitizing user input prevents potential security vulnerabilities. Storing cloud credentials directly in the app is not recommended for security reasons. Understanding these considerations is crucial for developing robust and secure file synchronization functionality in Flutter apps.
