In this tutorial you will learn how to add Navigation Drawer Layout in your Flutter App.

You will learn how to add Left Navigation Drawer ( Drawer which opens from start side or right side ) and right Navigation Drawer (Drawer layout which slides from end or left side of the screen).

We will be using following Widgets to add Drawer layout in our Flutter App:

  • Scaffold Widget.
  • ListView Widget.
  • Divider Widget.
  • ListTile Widget.
  • Text Widget.
  • Icon Widget.
  • UserAccountsDrawerHeader Widget.
  • Creating Scaffold

1. Creating Scaffold Widget

Scaffold is used to implement Drawer, Snackbar,  App Bar, Bottom Sheet, Bottom Navigation Bar and Floating Action Button.

So to add Navigation Drawer in our Flutter App we are required to add Scaffold Widget first.

Than our Drawer Widget will become children of Scaffold Widget (We will add drawer inside Scaffold).

Scaffold Widget has 2 properties for Drawer layouts in Flutter.

  • drawer (for Left to Right Navigation Drawer).  Drawer layout which expand from Left side.
  • endDrawer (for Right to Left Navigation Drawer).  Drawer layout which opens/expand from Right side.
Scaffold(
drawer: // Here we will add Drawer Layout.
);

Adding Drawer widget in Scaffold

Scaffold(
drawer: Drawer (
child: // here we will add Drawer layout items in next step.
), );

Adding List Items in Drawer

Here we will add ListView Widget as children of Drawer Widget.

We are adding ListView here so user can scroll drawer items vertically.

ListView Widget requires array of Wdgets as ListView items.

Scaffold(
drawer: Drawer(
elevation: 20.0,
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[


],
)),
)

Adding Header Layout in Drawer

At this step we are going to add first item in ListView which will be Drawer Header Layout.

For this purpose we have added UserAccountsDrawerHeader  Widget.

We can add user name, user email and user profile picture in our Drawer header.

Scaffold(
drawer: Drawer(
elevation: 20.0,
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
UserAccountsDrawerHeader(
accountName: Text('Hammad Tariq'),
accountEmail: Text('developine.com@gmail.com'),
currentAccountPicture:
Image.network('https://hammad-tariq.com/img/profile.png'),
decoration: BoxDecoration(color: Colors.blueAccent),
),
],
)),
)

This will be output of above code:

Adding Items in Drawer

Here we are

  • Adding on item click listener for Drawer item using onTap function.
  • Adding Icon widget for Drawer item.
  • Adding Text Widget for Drawer title.
  • Closing Navigation Drawer programatically.
  • Adding divider Widget after each drawer item (Line Divider).

Scaffold(
drawer: Drawer(
elevation: 20.0,
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
UserAccountsDrawerHeader(
accountName: Text('Hammad Tariq'),
accountEmail: Text('developine.com@gmail.com'),
currentAccountPicture:
Image.network('https://hammad-tariq.com/img/profile.png'),
decoration: BoxDecoration(color: Colors.blueAccent),
),

// Drawer layout first item.
ListTile(
leading: Icon(Icons.account_circle),
title: Text('Drawer layout Item 1'),
onTap: () {
// This line code will close drawer programatically....
Navigator.pop(context);
},
),
Divider(
height: 2.0,
),
],
)),
)

Adding Appbar (Toolbar) with Hamburger icon and Title

Flutter adding side menu icon (or hamburger icon) in flutter apps using appbar widget inside scaffold widget.
Flutter Appbar using Scaffold Widget

Simply add appBar using AppBar Widget and Flutter will make it like Toolbar and will also show hamburger icon.

If you want to center Appbar title use this property inside AppBar widget.

appBar: AppBar(
centerTitle: true,
title: Text('Developine App Bar'),
)

Hamburger icon is displayed by default because we have not provided any leading widget inside AppBar.

As our Scaffold widget has AppBar widget and our Drawer is inside AppBar so Flutter will place side menu icon (hamburger icon) automatically which will be used to open drawer.

If there is no drawer widget inside AppBar, Flutter will add back arrow here. which will be used to go back to screen or close app.

Completed Code

import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Drawer Layout Demo',
debugShowCheckedModeBanner: false,
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Flutter Drawer Demo Home Page'),
);
}
}

class MyHomePage extends StatelessWidget {
MyHomePage({Key key, this.title}) : super(key: key);

final String title;

@override
Widget build(BuildContext context) {
return Container(
child: new Scaffold(
appBar: AppBar(
title: Text('Developine App Bar'),
)
drawer: Drawer(
elevation: 20.0,
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
UserAccountsDrawerHeader(
accountName: Text('Hammad Tariq'),
accountEmail: Text('developine.com@gmail.com'),
currentAccountPicture:
Image.network('https://hammad-tariq.com/img/profile.png'),
decoration: BoxDecoration(color: Colors.blueAccent),
),
ListTile(
leading: Icon(Icons.account_circle),
title: Text('Drawer layout Item 1'),
onTap: () {
// This line code will close drawer programatically....
Navigator.pop(context);
},
),
Divider(
height: 2.0,
),
ListTile(
leading: Icon(Icons.accessibility),
title: Text('Drawer layout Item 2'),
onTap: () {
Navigator.pop(context);
},
),
Divider(
height: 2.0,
),
ListTile(
leading: Icon(Icons.account_box),
title: Text('Drawer layout Item 3'),
onTap: () {
Navigator.pop(context);
},
)
],
)),
));
}
}

Adding Right Drawer in Flutter

If you want to open drawer from right side of app like below:

Flutter endDrawer using Scaffold Widget Example.

Code for Right Drawer layout:

This code has slight change than above code.

Above code is using drawer property of Scaffold Widget, whereas below code will be using endDrawer property of Scaffold Widget.

import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Drawer Layout Demo',
debugShowCheckedModeBanner: false,
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Flutter Drawer Demo Home Page'),
);
}
}

class MyHomePage extends StatelessWidget {
MyHomePage({Key key, this.title}) : super(key: key);

final String title;

@override
Widget build(BuildContext context) {
return Container(
child: new Scaffold(
appBar: AppBar(
title: Text('Developine App Bar'),
)
endDrawer: Drawer(
elevation: 20.0,
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
UserAccountsDrawerHeader(
accountName: Text('Hammad Tariq'),
accountEmail: Text('developine.com@gmail.com'),
currentAccountPicture:
Image.network('https://hammad-tariq.com/img/profile.png'),
decoration: BoxDecoration(color: Colors.blueAccent),
),
ListTile(
leading: Icon(Icons.account_circle),
title: Text('Drawer layout Item 1'),
onTap: () {
// This line code will close drawer programatically....
Navigator.pop(context);
},
),
Divider(
height: 2.0,
),
ListTile(
leading: Icon(Icons.accessibility),
title: Text('Drawer layout Item 2'),
onTap: () {
Navigator.pop(context);
},
),
Divider(
height: 2.0,
),
ListTile(
leading: Icon(Icons.account_box),
title: Text('Drawer layout Item 3'),
onTap: () {
Navigator.pop(context);
},
)
],
)),
));
}
}
