Using a Drawer for Navigation

This example showcases how to implement a navigation drawer in a Flutter application.

dartCopy codeimport 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Drawer Navigation',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: HomeScreen(),
    );
  }
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Drawer Navigation')),
      drawer: Drawer(
        child: ListView(
          padding: EdgeInsets.zero,
          children: [
            DrawerHeader(
              decoration: BoxDecoration(color: Colors.blue),
              child: Text(
                'Navigation',
                style: TextStyle(color: Colors.white, fontSize: 24),
              ),
            ),
            ListTile(
              title: Text('Home'),
              onTap: () {
                Navigator.pop(context); // Close the drawer
              },
            ),
            ListTile(
              title: Text('Settings'),
              onTap: () {
                Navigator.push(
                  context,
                  MaterialPageRoute(builder: (context) => SettingsScreen()),
                );
              },
            ),
          ],
        ),
      ),
      body: Center(child: Text('Home Screen')),
    );
  }
}

class SettingsScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Settings')),
      body: Center(child: Text('Settings Screen')),
    );
  }
}
