Surviving Network Failures: Building Resilient Offline-First Flutter Apps

What happens when your app loses internet, does it gracefully adapt, or does it leave users frustrated? In a world where connectivity is unpredictable, building offline-first apps isn’t just a feature; it’s a necessity. In this talk, we’ll explore battle-tested strategies to keep your Flutter app running smoothly, even in airplane mode. You’ll learn: Caching Like a Pro – Choosing between SQLite, Hive, Isar, or ObjectBox for local data storage. Syncing Without Breaking Things – Ensuring data consistency with background sync techniques. Handling Conflicts Gracefully – Avoiding data loss when multiple devices update the same record. Background Tasks & Work Managers – Keeping data fresh even when the app isn’t open. By the end of this session, you'll walk away with practical solutions to handle network failures, data synchronization, and seamless user experiences, whether your app is used in the subway, remote villages, or just a bad Wi-Fi zone.
