Flutter Drawer Menu Navigation

Flutter Drawer Menu Navigation

A drawer menu is a common navigation pattern in mobile applications that provides easy access to different sections of your app. This guide will show you how to implement a beautiful and functional drawer menu in Flutter.

Why Use a Drawer Menu?

Drawer menus offer several advantages:

• Clean and organized navigation
• Easy access to main sections
• Consistent user experience
• Space-efficient design
• Familiar to users
• Scalable navigation structure

Implementation Steps

1. Create Drawer Menu

   class CustomDrawer extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return Drawer(
         child: ListView(
           padding: EdgeInsets.zero,
           children: [
             DrawerHeader(
               decoration: BoxDecoration(
                 color: Theme.of(context).primaryColor,
               ),
               child: Column(
                 crossAxisAlignment: CrossAxisAlignment.start,
                 children: [
                   CircleAvatar(
                     radius: 30,
                     backgroundImage: AssetImage('assets/profile.jpg'),
                   ),
                   SizedBox(height: 10),
                   Text(
                     'John Doe',
                     style: TextStyle(
                       color: Colors.white,
                       fontSize: 18,
                     ),
                   ),
                   Text(
                     'john.doe@example.com',
                     style: TextStyle(
                       color: Colors.white70,
                       fontSize: 14,
                     ),
                   ),
                 ],
               ),
             ),
             ListTile(
               leading: Icon(Icons.home),
               title: Text('Home'),
               onTap: () {
                 Navigator.pop(context);
                 Navigator.pushNamed(context, '/home');
               },
             ),
             ListTile(
               leading: Icon(Icons.person),
               title: Text('Profile'),
               onTap: () {
                 Navigator.pop(context);
                 Navigator.pushNamed(context, '/profile');
               },
             ),
             ListTile(
               leading: Icon(Icons.settings),
               title: Text('Settings'),
               onTap: () {
                 Navigator.pop(context);
                 Navigator.pushNamed(context, '/settings');
               },
             ),
             Divider(),
             ListTile(
               leading: Icon(Icons.logout),
               title: Text('Logout'),
               onTap: () {
                 // Handle logout
               },
             ),
           ],
         ),
       );
     }
   }
   

2. Implement in Scaffold

   class HomeScreen extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text('Home'),
         ),
         drawer: CustomDrawer(),
         body: Center(
           child: Text('Home Screen Content'),
         ),
       );
     }
   }
   

3. Add Navigation Routes

   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         title: 'Drawer Navigation Demo',
         theme: ThemeData(
           primarySwatch: Colors.blue,
         ),
         initialRoute: '/',
         routes: {
           '/': (context) => HomeScreen(),
           '/profile': (context) => ProfileScreen(),
           '/settings': (context) => SettingsScreen(),
         },
       );
     }
   }
   

4. Create Screen Components

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