Managing State in Flutter Pragmatically

By: RAHUL AGARWAL, Waleed Arshad

Overview of this book

Flutter is a cross-platform user interface (UI) toolkit that enables developers to create beautiful native applications for mobile, desktop, and the web with a single codebase. State management in Flutter is one of the most crucial and complex topics within Flutter, with a wide array of approaches available that can make it easy to get lost due to information overload. Managing State in Flutter Pragmatically is a definitive guide to starting out with Flutter and learning about state management, helping developers with some experience of state management to choose the most appropriate solutions and techniques to use. The book takes a hands-on approach and begins by covering the basics of Flutter state management before exploring how to build and manipulate a shopping cart app using popular approaches such as BLoC/Cubit, Provider, MobX, and Riverpod. Throughout the book, you'll also learn how to adopt approaches from React such as Redux and all its types. By the end of this Flutter book, you'll have gained a holistic view of all the state management approaches in Flutter, and learned which approach is the best solution for managing state in your app development journey.

Chapter 3: Diving into Advanced State Management Approaches

In the previous chapter, we learned how to create optimized screens that rebuild only the widgets required for user interaction. We also learned about two of the most basic and core implementations of state management techniques, which are setState and InheritedWidget.

In this chapter, we will study the two most popular state management techniques, which are Provider and BLoC, and their slight variations, Riverpod and Cubit, which make things easier for the developer. We will look at the following:

  • Provider – an easier implementation of InheritedWidget
  • Riverpod – a much easier version of Provider
  • BLoC – business logic component
  • Cubit – simplified BLoC

During your Flutter development journey, you are most likely going to use one of these techniques to build a state management solution for your application. So, it is highly recommended you understand each one of them...
