Project Structure:

You can see the following hierarchy: root > MyApp > MaterialApp > MyHomePage > Scaffold > Center, column, text, text, AppBar, Text, FloatinActionButton, Icon

[root]: This is the entry point for the Flutter application. Typically, in the main.dart file, you’ll find:

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false, // Remove DEBUG label
      home: Scaffold(
        appBar: AppBar(
          title: Text('My AppBar'),
          centerTitle: true, // Center text
          backgroundColor: Colors.blueAccent, // AppBar color
        ),
      ),
    );
  }
}
