Course Overview

Flutter is an innovative framework that allows developers to create high-quality mobile and web apps. Business logic component (BLoC) patterns allow Flutter applications to manage application state. You'll learn about the BLoC pattern and implement a counter application using streams, events, and states from the BLoC architecture. Next, you will learn to use different widgets provided by the BLoC library that help reduce the boilerplate code. You'll then implement a Star Wars project using the flutter_blo...Show More
