Flutter is a cross-platform UI toolkit developed by Google that allows developers to create apps for iOS, Android, web, desktop, and more from a single codebase written in Dart.

In Flutter, a widget is the basic building block of the user interface. Everything you see on the screen in a Flutter app—buttons, text, images, layouts, and even the whole screen itself—is made up of widgets.

Key points about Flutter widgets:

• Widgets describe the UI: They define how the app should look and behave.

• Everything is a widget: From simple elements like Text or Button to complex layouts like Row, Column, or Scaffold.

• Immutable and lightweight: Widgets are immutable, meaning their properties can’t change once created. To update the UI, Flutter rebuilds widgets efficiently.

• Composability: Widgets can be nested inside other widgets to create complex UIs.

• State full vs Stateless:

  • Stateless Widget: A widget that doesn’t hold or change state. It renders once based on its inputs.

  • State full Widget: A widget that maintains state that can change during the widget’s lifecycle, triggering UI updates.
