Building an offline first flutter app with supabase and powersync

okay, let's dive into building an offline-first flutter application using supabase and powersync. this will be a comprehensive guide with code examples, explanations, and best practices.

**i. introduction: the power of offline-first**

offline-first development is a paradigm shift in mobile and web development. instead of assuming a constant network connection, we build applications that prioritize local data storage and synchronization with a remote backend. this offers several key advantages:

* **enhanced user experience:** apps are responsive and available even without internet access. users can continue working, creating, editing, and interacting seamlessly.
* **improved performance:** local data access is significantly faster than fetching data from a remote server, resulting in a smoother and more performant application.
* **resilience:** offline-first apps can handle intermittent or unreliable network connections gracefully.

supabase and powersync are powerful tools that simplify the implementation of offline-first functionality in flutter.

* **supabase:** provides a scalable, open-source alternative to firebase. it offers authentication, a postgresql database, real-time subscriptions, edge functions, and storage.
* **powersync:** a local-first data synchronization platform that keeps your local database in sync with your remote database (supabase in our case). it handles conflict resolution, data versioning, and efficient data transfer.

**ii. prerequisites**

before we start, make sure you have the following installed:

* **dart sdk:** dart comes bundled with flutter.
* **android studio or xcode:** required for running and debugging the application on emulators or physical devices.
* **supabase account:** create a free account on supabase ([htt ...
