Create Navigation Drawer In Flutter

Navigation drawer is a UI panel which shows your app's main navigation menu. The navigation drawer appears when the user touches the interface icon in the app bar or when the user swipes a finger from the left edge on the screen. The navigation drawer slides show from the left and contain the navigation destinations for your app. You can see a complete description of navigation drawer Here. Before that we have been discussing about Face Detection In Flutter With MLKit And Firebase. Now, we will discuss how to create a navigation drawer in Flutter. Let's practice creating a menu drawer in flutter.

 

First, we must create new a project using Visual Studio Code software. Here's how to create a new project using Visual Studio Code:

• Invoke View > Command Palette.
• Type “flutter”, and select the Flutter: New Project.
• Enter a project name, such as myapp, and press Enter.
• Create or select the parent directory for the new project folder.
• Wait for project progress creation to complete and the main.dart file to appear.
• Add new folder path like this [projectname]/assets.

Edit file pubspec.yaml in your directory and it should look something like the below:

name: navigation_drawer
description: A new Flutter project.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
  - assets/camellab.png
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.io/custom-fonts/#from-packages

Modify file main.dart to completed like below,

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  final appTitle = 'Camellabs Demo';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: appTitle,
      home: MyHomePage(title: appTitle),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final String title;

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text(title)),
      body: Center(child: Text('My Page!')),
      drawer: 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: <Widget>[
            DrawerHeader(
              child: Text(
                'Drawer Header',
                style: TextStyle(color: Colors.white, fontSize: 22),),
              decoration: BoxDecoration(
                color: Colors.lightBlue[300],
              ),
            ),
            ListTile(
              title: Text('Menu 1', style: TextStyle(color: Colors.deepOrange),),
              onTap: () {
                // Update the state of the app
                // ...
                // Then close the drawer
                Navigator.push(
                  context,
                  MaterialPageRoute(builder: (context) => Menu1Page()),
                );
              },
            ),
            ListTile(
              title: Text('Menu 2', style: TextStyle(color: Colors.deepOrange),),
              onTap: () {
                // Update the state of the app
                // ...
                // Then close the drawer
                Navigator.push(
                  context,
                  MaterialPageRoute(builder: (context) => Menu2Page()),
                );
              },
            ),
          ],
        ),
      ),
    );
  }
}

class Menu1Page extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Menu 1 Page"),
      ),
      body: Center(
        child: RaisedButton(
          onPressed: () {
            Navigator.pop(context);
          },
          child: Text('Go back!'),
        ),
      ),
    );
  }
}

class Menu2Page extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Menu 2 Page"),
      ),
      body: Center(
        child: RaisedButton(
          onPressed: () {
            Navigator.pop(context);
          },
          child: Text('Go back!'),
        ),
      ),
    );
  }
}

After you have finished copying  the main.dart code, running the application will show the below output:
