Build an Offline First App using Flutter, Node, Bloc, Express, TypeScript, Docker and PostgreSQL!

In this video, we’ll build an offline-first task manager app using Flutter & Node step by step. The user will be able to sign up, log in, and have their logged-in state saved even after closing the app. They can create tasks, view tasks organized by date, and perform all these actions both online and offline. If they’re offline, the app will sync the data automatically with the remote database as soon as they go back online.
