Most mobile apps assume a stable internet connection, but the real world doesn’t work that way. Users expect apps to be reliable in trains, flights, basements, or areas with patchy data, and that’s where an Offline-First approach shines.
In this talk, I’ll walk through how Flutter developers can design apps that work seamlessly without network connectivity, and then sync data smoothly when online again. We’ll explore practical storage solutions (SQLite, Drift, Hive, Isar), caching patterns, sync strategies, and handling tricky issues like data conflicts.
The session will mix architecture concepts with real-world code examples, showing how to build a simple but production-ready notes app that stays functional offline and updates itself automatically once reconnected.
By the end, you’ll see how Offline-First design improves user experience, reliability, and adoption, and how Flutter’s ecosystem makes it easier than ever to achieve.
