what is scaffold in flutter

In Flutter, a Scaffold is a class that provides a framework for implementing the basic material design visual layout structure of a mobile application. It is a top-level container for a MaterialApp and provides APIs for showing drawers, snack bars, bottom sheets, app bars, floating action buttons, and more. The Scaffold class is designed to expand or occupy the whole device screen and provides a framework to implement the basic material design layout of the application. The Scaffold widget is able to occupy the whole device screen and is mainly responsible for creating a base to the app screen on which the child widgets hold on and render on the screen. The Scaffold class is a shortcut to set up the look and design of an app, which saves time and effort in writing more code for the look and feel of the app. The Scaffold class has several properties, including appBar, body, floatingActionButton, floatingActionButtonLocation, floatingActionButtonAnimator, persistentFooterButtons, drawer, endDrawer, bottomNavigationBar, bottomSheet, backgroundColor, resizeToAvoidBottomPadding, resizeToAvoidBottomInset, primary, drawerDragStartBehavior, extendBody, and drawerScrimColor.
