Answer
Scaffold is a Material Design layout widget that implements the basic visual structure of a screen. It provides named slots for common UI elements: appBar for the top app bar, body for the main content, drawer for a slide-in navigation menu, bottomNavigationBar, floatingActionButton, and more. Using Scaffold ensures your screen follows Material Design guidelines without building every component from scratch.
