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.

Summary

We learned about two approaches from React in this chapter: Redux and MobX. Both of the approaches used reactive-style programming where you create actions and listen through observables. To summarize, we have the following:

  • Redux uses a unidirectional data flow to manage the state in your Flutter app.
  • Redux uses a single store that keeps the whole state of your application.
  • MobX uses the autogeneration of state management code, hence it is easier to understand and implement.
  • The build_runner command generates the part of the file that is connected to the class created by us.

The two React-adopted techniques we learned about in this chapter are going to be helpful to you if you are coming from a React background and have used Redux in your React projects very often. Also, if you want to experience how autogeneration is helpful in large-scale apps, MobX is going to be your go-to technique.

In the next chapter, we will be studying some distinctive...
