Offline sync patterns for mobile apps (Flutter)
Published 2026-02-06 · 9 min read
Queues, conflict resolution, and UX honesty when connectivity is unreliable—patterns for India-first mobile products.
UX principles
Tell users what is pending, what failed, and what will retry. Avoid silent data loss—trust erodes faster than features ship.
Technical patterns
Idempotency keys, optimistic UI with rollback, and durable local queues are foundational.
Testing
Simulate flaky networks in QA; measure sync recovery time after airplane mode toggles.
Frequently asked questions
- CRDT everywhere?
