Flutter State Management refers to the data that controls the behavior and the appearance of the application UI. The state in the app changes in response to the user input, and the triggered events, and for developers, it’s critical to manage the state effectively to build responsive and performant apps.
Managing states helps developers to keep their code organized and maintained as the app's complexity grows. Moreover, state management avoids code duplication and ensures that state changes are propagated throughout the app constantly. This simplifies adding new features, bug fixing, and other customization to the UI.
To make state management smoother there are several stateful state management approaches in Flutter, ranging from the simple solution like setState(), to more complex tools such as BLoC, Provider, Riverpod, MobX, and GetX. Each of these approaches has its own strengths and weaknesses.
So, if you are looking for the best state management packages for your next Flutter project in 2023. This article can help you to explore more about the top Flutter State Management packages that can help you build a high-quality Flutter application.
There are several popular state management packages available for Flutter. Here are some of the most commonly used and highly recommended state management packages for Flutter:
Let’s look into each of them in detail..
BLoC is an advanced solution that provides a high level of control and predictability but can be complex to implement. It is a popular state management solution that separates the presentation layer of an app from the business logic with the BLoC Layer. The BLoC layer acts as a bridge between the UI layer and the data layer.
It takes input from the UI layer, processes it, and sends output to the UI layer. The UI layer is only responsible for displaying the data and user interactions, while the BLoC layer is responsible for maintaining the application state and making decisions based on that state.
The BLoC layer handles the business logic of an application and communicates with the presentation layer through streams. The basic idea behind the BLoC pattern is to break an application down into small, reusable, and testable components, each with its responsibility.
Overall, the BLoC is a design pattern that helps manage the app state in a modular and testable way. BLoC is an effective way to handle complex state management scenarios in Flutter applications.
This package is a lightweight and flexible solution for managing state in Flutter apps. The provider works well for both small and large-scale apps and provides a simple API for managing states that can be easily understood and implemented.
In context, a provider is a class that holds some state and exposes it to other parts of the application that need to use it. This state can be any type of data, such as a boolean value, a list of items, or even an entire object.
When a provider is used, it is typically wrapped around the widget tree that needs access to the state it manages. This allows the state to be accessed and updated by any child widget that needs it.
As a result, changes to the state are automatically propagated throughout the widget tree, without the need for manual updates or callbacks.
Riverpod is a package built on top of Provider that provides an improved API for managing state in Flutter apps. It's built on top of the provider package and offers better performance, scoping, and testability.
With Riverpod, you can define your application state as a series of providers, which are objects that expose a value and can be used to read or modify that value throughout your application. Providers can depend on other providers, which makes it easy to compose complex state management logic.
Riverpod provides a range of features that can help you to build maintainable and scalable Flutter applications, such as:
This is how Riverpod provides a flexible and powerful way to manage state in Flutter, with a range of features that can help you to build maintainable and scalable applications.
GetX is a state management package that provides a full-featured solution for managing the state in Flutter apps, along with navigation and dependency injection. GetX is easy to use, fast, and well-documented, making it a popular choice for many Flutter developers.
Though GetX is primarily focused on state management, it also includes other functionalities, such as dependency injection, routing, and more.
In terms of state management, GetX offers a reactive approach that makes it easy to handle state changes in your Flutter application. It provides a simple and concise API for managing state using observables, reactions, and actions.
As a whole, GetX provides a simple and efficient approach to state management in Flutter, with a range of additional features that can help you to build robust and maintainable applications.
MobX is a state management library that uses reactive programming to manage state in Flutter apps. It's well-suited for complex apps with large amounts of state and provides a simple, easy-to-use API. It utilizes observables and reactions to automatically update the user interface in response to changes in the application state.
In Flutter, MobX can help simplify state management by reducing the amount of boilerplate code required to handle state changes. It achieves this by using a reactive programming model that automatically updates the user interface whenever the state changes.
Altogether the MobX package can help make state management in Flutter more efficient and easier to maintain by automating much of the manual work involved in keeping the UI in sync with the application state.
In the article, we have learned about the top Flutter State Management Packages and their benefits. Ultimately, the choice of which state management package to use in your Flutter project depends on your specific requirements and preferences.
Each of these packages has its own strengths and weaknesses, so it's important to evaluate them carefully to determine which one is the best fit for your project.
Well, if you are using DhiWise Flutter builder, and worrying about state management be rest assured. As the platform provides you with inbuilt support for GetX approach as well as the Stateless approach. So, now managing state with Flutter builder is going to be easier than ever.
