Hi Guy’s, Welcome to Proto Coders Point. In this flutter tutorial let’s create a Sidebar Navigation Menu using a package i.e. Flutter SidebarX.

Flutter SidebarX

Let’s get started

In flutter there are two ways to create a navigation i.e. by tabs & Drawer. I found out a flutter package that is recently launched SideBarX using which flutter app developer can easily create multiplatform navigation drawer sidebar/ sidebar menu / side navigation drawer.

Sidebar Navigation menu is very useful for user for in-app navigation(page routing) or for user profile.

In this flutter tutorial Article let’s create a simple sidebar navigation menu by using flutter sidebarX package.

1. Create a new Flutter project or open any existing to implement sidebarX

I use Android Studio to build flutter application, you can use your favorite IDE.

create Project -> Android Studio -> File -> New -> New Flutter Project -> Give Project Name -> create project by click Finish.

2. Add/Install SidebarX package as dependencies

In your project structure look for file by name pubspec.yaml, Open it & under dependencies section add sidebarx package, as shown in below screenshot.

click on pub get to download the package as external libraries.

3. Import SidebarX

Once the sidebarx dependencies is added into you flutter project as external libraries, To use it you need to import it.

import 'package:sidebarx/sidebarx.dart';

4. SidebarX Widget Properties

5. Sidebarx widget snippet code

1. For Mobile Devices – Small Screen

Scaffold(
      drawer: SidebarX(
        controller: SidebarXController(selectedIndex: 0, extended: true),
        items: const [
          SidebarXItem(icon: Icons.home, label: 'Home'),
          SidebarXItem(icon: Icons.search, label: 'Search'),
        ],
      ),
      body: const Center(child: Text('Your app body')),
)

2. For Browser or Platform app – Big Screen

Scaffold(
      body: Row(
        children: [
          SidebarX(
            controller: SidebarXController(selectedIndex: 0),
            items: const [
              SidebarXItem(icon: Icons.home, label: 'Home'),
              SidebarXItem(icon: Icons.search, label: 'Search'),
            ],
          ),
          // Your app screen body
        ],
      ),
   )
