What is State Management in Flutter?

The art of managing your app's data and user interface as it changes over time in Flutter is known as state management. Consider it as an orchestra conductor, bringing the data, the visual components, and the user's interactions together in perfect harmony. Developers can create gorgeously dynamic and responsive user experiences with the help of Flutter, a flexible and strong framework for creating cross-platform apps. Effective state management is essential for achieving this, though.

State management primarily entails storing and modifying data that your app needs to function, such as user preferences, real-time data from APIs, or the state of the user interface (UI). To accomplish this, Flutter provides various tools and methods, ranging from the straightforward yet efficient setState function for small apps to more intricate ones like the BLoC (Business Logic Component) pattern or third-party libraries like Provider. The decision depends on your app's particular requirements and scale, as each strategy performs a different function.

In Flutter, maintaining data consistency, ensuring that the user interface appropriately reflects the underlying data, and improving efficiency while delivering a seamless and enjoyable user experience are the major goals of state management.

Alex nodded, "But why is it required? What's the big deal?"

Alena leaned in and replied.

Why is State Management Required?

Because it enables us to centralize all UI states and regulate data flow in the application, state management is crucial to Flutter app development. When a user first signs up, you might send them a welcome message, but you don't want to show it to them for the next two years or until they cease using the app. Because of this, if we explain how to handle the state on every page, we risk code problems. Code duplication will also happen as a result.

This message should only be displayed after the user registers as part of state management and UI control.

Here are the issues solved by state management:

  • What should we do with a page after the user clicks the URL's refresh button?
  • What do we do after the server updates or refreshes its data?
  • How do components and services learn about the state?
  • How do we ask the server to update the page?

The state management process enables us to understand our program, the user's location, activities, and the data they enter.

Alex was beginning to understand the importance of this concept. "Alright, so what are the types to get State Management in Flutter? There seem to be so many options."

Alena listed the options one by one, “The approach you choose for managing the state in Flutter will depend on the requirements of your app. Provider, GetX, Riverpod, Stateful Widget, Bloc (Business Logic Component), Inherited Widget, and Redux are some of the most well-liked ones. Each of these has distinct features and applications.”

What are the Types of State Management in Flutter?

Provider is a popular state management solution for Flutter. It enables you to design and control providers that store the application's state. To detect changes in the state, widgets can then listen to these providers. Provider is useful for controlling shared or global state.


For Flutter, GetX is a strong and compact state management library. It offers a straightforward, high-performance method for handling navigation, managing state, and injecting dependencies. GetX is renowned for its effectiveness and simplicity.


Riverpod is a state management technique similar to Provider. Unlike Provider, it uses a unidirectional data flow to help overcome difficulties like readability, testability, performance, etc. Developers are spared from handling runtime exceptions because it only detects issues during compilation. Riverpod also stays independent of BuildContext.

Stateful Widgets

Flutter has a built-in approach for handling state called Stateful Widgets. 'StatefulWidget' and 'State' are the two classes that make them up. While the 'State' object contains the mutable state data, the 'StatefulWidget' represents the widget's immutable component. Calling'setState()' causes a rebuild of the widget, changing the UI when the state data changes.

Bloc (Business Logic Component)

The Bloc (Business Logic Component) pattern is frequently utilized for state management in Flutter, especially for complicated applications. It employs streams to manage and communicate state changes and isolates the UI from the business logic. Many people use the 'flutter_bloc' package to implement the Bloc pattern.

Inherited Widget

InheritedWidget state management's base class transfers relevant information to the tree's offspring. Anyone underneath this widget will instantly inherit its properties because of its top-to-bottom architecture. This structure is difficult, though, if your app is quite large.


Redux is a state management structure that adheres to the separation of concerns, or presentation and business logic, using a unidirectional data flow. Redux isolates different app components, making UI updates considerably simpler and debugging much easier. This is the finest state management in terms of synchronous app logic.

Alex was curious. There are a ton of options. How do I choose the best one?

Alena reassured him, "Choosing the best state management strategy can be difficult, but it all depends on the demands of your project. You must consider the app's complexity, your team's skill level, and your project's requirements. The ideal option varies depending on the project."

Alex was excited to learn about state management best practices after having a better grasp.

Alena shared her insights!

Best Practices for State Management in Flutter

Consider Code Generation

The boilerplate code you must write can be reduced using tools like json_serializable and freeze. They save you time and lower the possibility of errors by generating code for serialization, data classes, and other things.

Understand Flutter’s Built-In State Management

Options for managing states that are included in Flutter include setState, InheritedWidget, and ValueNotifier. Learn about these choices and employ them when they meet the needs of your project. The lightweight built-in solutions of Flutter can be a wonderful place to start for basic apps.

Organize your Code

Keep your codebase organized and clean. Separate your issues into digestible chunks of code by adhering to this guideline. Separate the UI, business logic, and data layers using the BLoC design or another architectural pattern.

Use Immutable Data

Immutable data cannot be altered once it is generated. When modifications are required, you can leverage immutable data structures in Flutter, like the final and copyWith methods, to generate new objects. This guarantees data uniformity and assists in avoiding unwanted side effects.

Optimize Performance

A major component of state management is performance. Make sure the UI modifications in your app are effective. Use the shouldRebuild method for Consumer widgets, the const constructors for widgets, and the const keyword for widgets that don't change to improve efficiency.

State Management for Network Requests

Handle state changes gracefully when dealing with network requests and asynchronous operations. Make HTTP requests using FutureBuilder or other libraries like Dio. To give users a seamless experience, implement loading, success, and error statuses.

Error Handling

Managing the state in Flutter is critically dependent on error handling. Be ready to accept failure gently. Provide users with helpful error messages, keep a log of problems for troubleshooting, and think about utilizing try-catch blocks or async/await for asynchronous activities. Use third-party libraries or global error handlers to centralize and streamline error management.

As they finished their coffee, Alena concluded, "State management in Flutter can be challenging, but with the right approach, it becomes a powerful tool to build responsive and effective apps." You'll be on the correct track if you keep in mind these excellent practices.
