Going Offline first with Flutter
summary
Shows a concrete offline-first architecture for Flutter using a local SQLite-backed single source of truth, a background sync manager reading a pending sync operations table, and HTTP APIs or BaaS (Firebase/Realm) for server-side sync. Demonstrates optimistic UI updates and paginated delta updates with timestamps, outlines conflict strategies from last-write to CRDTs, recommends packages (sqflite/hive/drift, CRDT libraries) and a “three attempts then revert” retry rule, and cites WorkManager for background execution.
