Overview

This course takes you from the fundamentals of Dart to complete, production-quality Flutter applications. You will learn how modern apps are structured — widgets, state, navigation, data and APIs — by building real projects rather than isolated exercises. State is handled the way production teams handle it: with the BLoC pattern, separating business logic from the interface so an app stays testable as it grows.

By the end, you will have designed, built and prepared a multi-screen app for release, using the same tools and practices professional teams use to ship apps to the App Store and Google Play.

Who it's for

  • Beginners who want to build their first real mobile app
  • Web developers moving into mobile development
  • Students who want a practical, portfolio-ready project

Before you start

  • Comfort using a computer and installing software
  • No prior mobile development experience required
  • Basic programming familiarity helps, but is not essential
