Building Offline-First Apps with Flutter
How to design Flutter apps that work seamlessly without an internet connection using local databases and sync strategies.
In markets like Indonesia, reliable internet isn’t guaranteed. Offline-first design is essential.
Local Storage Options
- Hive — Fast, lightweight, no native dependencies
- Drift — Type-safe SQLite with reactive queries
- Isar — High performance, supports complex queries
Sync Strategies
- Queue mutations locally and replay when online
- Use timestamps or version vectors for conflict resolution
- Show clear UI indicators for sync status
User Experience
Users shouldn’t even notice they’re offline. Cache aggressively, sync transparently, and handle conflicts gracefully.
