FAQ
Which local database do you use for Flutter caching?
I primarily use Hive or Isar for lightning-fast key-value/NoSQL storage, and Sqflite for relational data. If your project already uses a specific database, I can adapt to your existing tech stack.
Can you make my existing API-driven app work fully offline?
Yes! I can implement a repository pattern that serves cached data instantly when offline and fetches fresh data from your REST API or Firebase when an internet connection is detected.
Will adding data caching make my app size significantly larger?
No. The code footprint is minimal. For the cached data itself (like text or images), I set strict maximum storage limits and automatic cleanup rules so it won't clutter your users' device storage.
Do you need access to my backend or source code?
Yes, I will need access to your Flutter repository. For backend APIs, you can provide the API documentation (Swagger/Postman) or a staging environment so I can test the caching mechanisms safely.
