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.

Riverpod – enhancing Provider

As Flutter frameworks got better with time, state management packages were also enhanced, and problems caused by older techniques were solved in newer ones. Riverpod is an enhancement of the Provider package. It uses the concepts of Provider underneath and adds to the functionality by providing improved flexibility and performance. One major problem that Riverpod solved was having the possibility of reading null objects from the states. Reading objects in Riverpod is now compile-safe, so you are always sure that you won't get a null when reading objects from states using read or watch functions. You can read more about Riverpod and its documentation on its official website at https://riverpod.dev/.

In this section, you are going to learn how to consume a Riverpod package inside your counter example application. You will also learn some new keywords that would be similar to the functionality discussed in the previous section.
