Now that you have a Drawer in place, add content to it. |
For this example, use a ListView. |
While you could use a Column widget, |
ListView is handy because it allows users to scroll |
through the drawer if the |
content takes more space than the screen supports.Populate the ListView with a DrawerHeader |
and two ListTile widgets. |
For more information on working with Lists, |
see the list recipes. |
<code_start>Drawer( |
// Add a ListView to the drawer. This ensures the user can scroll |
// through the options in the drawer if there isn't enough vertical |
// space to fit everything. |
child: ListView( |
// Important: Remove any padding from the ListView. |
padding: EdgeInsets.zero, |
children: [ |
const DrawerHeader( |
decoration: BoxDecoration( |
color: Colors.blue, |
), |
child: Text('Drawer Header'), |
), |
ListTile( |
title: const Text('Item 1'), |
onTap: () { |
// Update the state of the app. |
// ... |
}, |
), |
ListTile( |
title: const Text('Item 2'), |
onTap: () { |
// Update the state of the app. |
// ... |
}, |
), |
], |
), |
);<code_end> |

4. Close the drawer programmatically |
After a user taps an item, you might want to close the drawer. |
You can do this by using the Navigator.When a user opens the drawer, Flutter adds the drawer to the navigation |
stack. Therefore, to close the drawer, call Navigator.pop(context). |
<code_start>ListTile( |
title: const Text('Item 1'), |
onTap: () { |
// Update the state of the app |
// ... |
// Then close the drawer |
Navigator.pop(context); |
}, |
),<code_end> |

Interactive example |
This example shows a Drawer as it is used within a Scaffold widget. |
The Drawer has three ListTile items. |
The _onItemTapped function changes the selected item’s index |
and displays the corresponding text in the center of the Scaffold.info Note |
For more information on implementing navigation, |
check out the Navigation section of the cookbook. |
<code_start>import 'package:flutter/material.dart'; |
void main() => runApp(const MyApp()); |
class MyApp extends StatelessWidget { |
const MyApp({super.key}); |
static const appTitle = 'Drawer Demo'; |
@override |
Widget build(BuildContext context) { |
return const MaterialApp( |
title: appTitle, |
home: MyHomePage(title: appTitle), |
); |
} |
} |
class MyHomePage extends StatefulWidget { |
const MyHomePage({super.key, required this.title}); |
final String title; |
@override |
State<MyHomePage> createState() => _MyHomePageState(); |
} |
class _MyHomePageState extends State<MyHomePage> { |
int _selectedIndex = 0; |
static const TextStyle optionStyle = |
TextStyle(fontSize: 30, fontWeight: FontWeight.bold); |
static const List<Widget> _widgetOptions = <Widget>[ |
Text( |
'Index 0: Home', |
style: optionStyle, |
), |
Text( |
'Index 1: Business', |
style: optionStyle, |
), |
Text( |
'Index 2: School', |
style: optionStyle, |
), |
