Example Concept: Offline data synchronization typically uses a pattern where local data changes are queued and stored in a local database (e.g., SQLite, Room, Core Data). When the device regains connectivity, a background service or task processes these queued changes, sending them to the server via RESTful APIs or GraphQL. Conflict resolution strategies, such as last-write-wins or custom merge logic, are implemented to handle discrepancies between local and server data.
