Complete detail about Flutter state managements in the flutter

In general, there are several state management techniques that can be used in Flutter to manage the state of a widget or application. These include:

  1. setState
  2. InheritedWidget
  3. ScopeModel
  4. Provider
  5. GetX
  6. Bloc
  7. MobX
  8. RiverPod
  9. Redux
  10. GetIt
  11. Binder
  12. Flutter Commands
  13. states_rebuilder
  14. Triple Pattern (Segmented State Pattern)

setState

setState is a built-in method provided by Flutter that allows a widget to mark itself as “dirty” and requires a rebuild. It is typically used for simple state management needs and is suitable for small or medium-sized applications.

InheritedWidget

InheritedWidget is a widget that allows its descendant widgets to access its state. It can be used to share data between widgets in the widget tree and is suitable for simple state management needs.

ScopeModel

ScopeModel package provides a simple and efficient way to share data across the widget tree. It is suitable for medium-sized applications and allows widgets to rebuild automatically when the model changes.

Provider

The provider package also provides a simple and efficient way to share data across the widget tree. It is suitable for large applications and allows widgets to rebuild automatically when the provider changes.

GetX State Management

GetX state management library for Flutter provides a simple and efficient way to manage the state of your application. It is based on the reactive programming model, which means that it allows you to specify how the state of your application should change in response to user actions or events across the application.

GetX provides a number of features that make it easy to manage the state of your application, including Obx, GetXController, GetX<T>

Bloc State Management

Bloc pattern that separates the business logic of an application from its presentation layer. It is much more suitable for large applications and allows widgets to rebuild automatically when the stream of data they are listening to changes.

MobX

MobX package provides a reactive way to manage the state of an application. It is suitable for large applications and allows widgets to rebuild automatically when the state they are observing changes.

Riverpod

Riverpod state management library for Flutter applications. It provides a simple, predictable way to manage the state of your Flutter app by using providers and dependency injection.

Riverpod makes it easy to manage the state of your Flutter app by providing a simple and predictable way to access and update the state of your app. It also helps to make your code more modular and reusable by allowing you to define and inject dependencies throughout your app.

Redux

Redux is a popular state management library that can be used in Flutter applications to manage the state of the app. To use Redux in a Flutter app, you will need to install the flutter_redux package.

This package provides a Store class that holds the state of the app and a StoreConnector widget that can be used to build widgets that depend on the state.

To use flutter_redux in your Flutter app, you will need to create a Redux store and define your reducers.

GetIt

GetIt is a simple service locator for Flutter applications that can be used to manage the state of the app.

To use GetIt in a Flutter app, you will need to install the get_it package. This package provides a GetIt instance that you can use to register and retrieve objects.

GetIt is a simple and lightweight solution for managing state in Flutter apps, but it does not provide the same level of features and functionality as a more full-featured state management library like Redux.

Binder

Binder is a state management library for Flutter that uses the reactive programming paradigm to manage the state of the app. It provides a simple and powerful way to manage the state, but it may require a different mental model for those unfamiliar with reactive programming.

To use Binder in a Flutter app, you will need to install the binder package. This package provides a Binder class that you can use to create reactive values and streams, and bind them to your widgets.

Flutter Commands

In Flutter, the Command pattern can be used to manage the state of the app.

The Command pattern is a design pattern that separates an action from the object that invokes the action. It consists of a command object and a receiver object.

The command object contains the logic for the action, and the receiver object contains the state that the action will be applied.

The Command pattern can be a useful way to manage a state in a Flutter app, but it can be more complex to set up and use than some other state management solutions.

states_rebuilder

states_rebuilder is a state management library for Flutter that uses the reactive programming paradigm to manage the state of the app. To use states_rebuilder in a Flutter app, you will need to install the states_rebuilder package.

This package provides an Inherited Widget called Injector that you can use to create reactive values and streams, and bind them to your widgets.

states_rebuilder is a reactive state management library that can be used to manage the state of a Flutter app. It provides a simple and powerful way to manage the state, but it may require a different mental model for those unfamiliar with reactive programming.

Triple Pattern (Segmented State Pattern)

The Triple Pattern is a design pattern that can be used to manage the state of a Flutter app. The Triple Pattern consists of three classes: the model, the view, and the controller.

The model contains the state of the app, the view displays the state to the user, and the controller updates the state in response to user input.

To use the Triple Pattern in a Flutter app, you can define a class for the model, a widget for the view, and a widget for the controller.
