Problem Statement
What is the purpose of the Scaffold widget?
Explanation
Scaffold implements the basic Material Design visual layout structure, providing a framework for common Material Design components like AppBar, BottomNavigationBar, FloatingActionButton, Drawer, and SnackBar. It's typically the root widget of each screen in Material Design apps.
Scaffold handles many Material Design layout concerns automatically, like proper spacing, automatic padding for system UI (status bar, notches), and coordinating animations between different components. The body property contains the main content, while other properties add standard UI elements around it.
Common Scaffold properties include appBar for the top app bar, body for main content, floatingActionButton for the FAB, bottomNavigationBar for bottom nav, drawer for side menu, and backgroundColor for the scaffold background. Using Scaffold ensures your app follows Material Design guidelines and provides a consistent structure across screens.
