Requires a bit of setup and more boilerplate codeĬan become difficult to manage and scale for large projects 2. Provides a simple and efficient way to share data to the widget tree It works by telling registered build references when a change occurs. It’s a base class for widgets that efficiently propagate information down the tree. Here are the most popular libraries used to manage app state in a Flutter:įlutter framework offers an Inherited Widget to simplify the application state. because it needs to be shared throughout the application.įor managing the app state, you have to use a state management solution (inherited widget or third-party library).
When your state variables are outside of the Stateful widget, it’s known as App state. In simple words there is no need to use state management solutions like (BLoc, Provider etc).Ģ.Current percentage of Loading indicator. You can manage the ephemeral state using the setState method. It’s the local state ( i.e UI state ) that holds a particular state inside the Stateful widget, and is associated with a single widget and always placed inside the state class. In Flutter, there are two states in an application. To keep track of the various pieces of data that are used by an application, the Flutter state management library helps you manage app data and change in states. Why do we need state management libraries?Įvery app has to share data and variables across the app in Flutter. It means whenever the application state changes, Flutter rebuilds the UI. Flutter uses a reactive programming model where the user interface is rebuilt whenever the state changes. In Flutter, a state refers to the data that can change during the lifetime of the widget. Why do we need state management libraries?.
