Basic Flutter Program Explained

  • The import ‘package:flutter/material.dart’; means we’re using the Material design package from Flutter.
  • The void main() {…} function is where every Flutter application starts.
  • The runApp(…); function is how we initialize and launch the app’s UI.
  • The MaterialApp widget is our foundation for creating Material Design apps in Flutter.
  • The Scaffold widget provides a basic visual structure, like a canvas, to design our app upon.
