Offline-first sync in Flutter: how do I resolve conflicts between phone and server?

dart flutter hors-ligne offline-first

Field agents edit the same record on the phone and in the web back-office. After a sync, one version silently overwrites the other.

For data where conflicts are rare, last-write-wins is acceptable if you log what was overwritten. For critical data such as stock or balances, send operations (+3 units) instead of final values, so concurrent changes add up instead of overwriting.

Add a version (or updated_at) column and send the version you edited with every update. The server rejects the update with 409 Conflict when versions differ, and the app then shows both values to the user or merges field by field.
