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 8: Using GetX, GetIt, and Binder to Update the Cart Application

In this chapter, we will be looking into how to create a cart application using the following approaches, which were studied in the previous chapters:

  • GetX
  • GetIt
  • Binders

We will be going through all the concepts and code snippets discussed in Chapter 5, Executing Distinctive Approaches like GetX, GetIt, and Binder. We are going to create the same screens we created in the previous chapter but with an updated technique. So, technically the output of every technique will be the same (a cart application where you can add/remove items from the cart) but with entirely different code running behind each technique.

By the end of this chapter, you will be able to create Flutter apps from scratch using the three state-management techniques mentioned previously. You will also be provided with an optional challenge to get your brains...
