As you know in Flutter all the UI components are known as widgets. The widget which contains the code for a single screen of the app can be just of two types

  • Stateful
  • Stateless
Stateless:

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

Stateful:

Stateful widgets have a mutable state, i.e., they are mutable and can be drawn multiple times within their lifetime. They are the widgets that can change their state multiple times and can be redrawn onto the screen any number of times while the app is in action.

This is all it takes to get your Stateful Widget started!
