How can I implement offline data syncing in a Flutter app?

Asked on Dec 07, 2025

Answer

Implementing offline data syncing in a Flutter app involves managing local data storage and ensuring synchronization with a remote server when connectivity is restored. This can be achieved using packages like `sqflite` for local storage and `http` or `dio` for network requests.

Example Concept: Offline data syncing in Flutter typically uses a local database (e.g., SQLite) to store data when offline. The app listens for connectivity changes, and upon regaining network access, it synchronizes the local data with a remote server using RESTful APIs. This approach ensures data consistency and availability even without an internet connection.

Additional Comment:

Use `connectivity_plus` to detect network changes and trigger sync operations.
Implement a queue or a task scheduler to manage pending network requests.
Handle conflicts by implementing a conflict resolution strategy, such as last-write-wins or user-defined rules.
Test the syncing logic thoroughly to ensure data integrity during network transitions.
