How to Make Reusable App Bar and Drawer in Flutter
Introduction
Flutter has become a popular framework for mobile app development due to its ease of use and flexibility. One of the key features of a Flutter app is the App Bar and Drawer, which provides navigation and other essential features to the user. In this blog post, we will explore how to create a reusable App Bar and Drawer in Flutter, which can be used throughout the app.
Creating Reusable App Bar
To create a reusable App Bar, we can create a separate widget that contains the App Bar code. This widget can then be used in any screen that requires an App Bar. Here is an example of how to create a reusable App Bar:
“`dart
class CustomAppBar extends StatelessWidget {
final String title;
CustomAppBar(this.title);
@override
Widget build(BuildContext context) {
return AppBar(
title: Text(title),
);
}
}

Creating Reusable Drawer
To create a reusable Drawer, we can create a separate widget that contains the Drawer code. This widget can then be used in any screen that requires a Drawer. Here is an example of how to create a reusable Drawer:
“`dart
class CustomDrawer extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Drawer(
child: ListView(
children: [
ListTile(
title: Text(‘Home’),
onTap: () {
Navigator.pushReplacementNamed(context, ‘/’);
},
),
ListTile(
title: Text(‘Settings’),
onTap: () {
Navigator.pushReplacementNamed(context, ‘/settings’);
},
),
],
),
);
}
}

Using Reusable App Bar and Drawer
Once we have created the reusable App Bar and Drawer, we can use them in any screen that requires them. Here is an example of how to use the reusable App Bar and Drawer:
“`dart
class HomeScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: CustomAppBar(‘Home Screen’),
drawer: CustomDrawer(),
body: Center(
child: Text(‘Home Screen’),
),
);
}
}
“`
