What is state of a widget?

Stateless widgets do not require mutable state, i.e., it is immutable. In simple words, Stateless widgets cannot change their state during the runtime of the app, which means the widgets cannot be redrawn while the app is in action.

Widgets describe what their view should look like given their current configuration and state . It includes a text widget, row widget, column widget, container widget, and many more. Widgets: Each element on a screen of the Flutter app is a widget.

State can be described as “whatever data you need in order to rebuild your UI at any moment in time “. When the state of your app changes (for example, the user flips a switch in the settings screen), you change the state, and that triggers a redraw of the user interface.
