What is stateful vs stateless?

Below is the basic structure of a stateless widget. Stateless widget overrides the build() method and returns a widget . For example, we use Text or the Icon is our flutter application where the state of the widget does not change in the runtime.19 Mar 2021

Stateful services keep track of sessions or transactions and react differently to the same inputs based on that history. Stateless services rely on clients to maintain sessions and center around operations that manipulate resources, rather than the state.

A widget is either stateful or stateless. If a widget can change—when a user interacts with it, for example—it’s stateful. A stateless widget never changes . Icon , IconButton , and Text are examples of stateless widgets.
