Introduction

State means the data or the properties of an app that can change over time. State management is the process of managing and updating the state in your app.

Info

Note: Proper state management helps you build scalable and maintainable Flutter apps.

Why State Management?

You should use state management in your Flutter apps to:

  • Keep UI and business logic separate.
  • Keep your app’s UI in sync with its data.
  • Update the UI in response to user interactions or other events.
  • Manage app-wide state and data.

State Management Approaches in Flutter

Flutter offers multiple ways to manage state, including:

  • Local State Management: Using StatefulWidget to manage state within a widget.
  • Global State Management: Managing app-wide state using solutions like Provider, Riverpod, Bloc, and more.

Here are some popular state management packages for Flutter:

  • Provider: A simple and effective way to manage app-wide state.
  • Riverpod: A provider package that offers a more powerful and flexible way to manage state.
  • Bloc: A predictable state management library that helps you manage app state and UI separately.
  • GetX: A lightweight and fast state management solution for Flutter.
