Introduction

When building a Flutter app, one of the most common requirements is to have a persistent navigation drawer that is accessible across all pages. This can be achieved by creating a custom Drawer widget and using it throughout your app. In this article, we will explore how to create a persistent AppBar drawer in Flutter that can be accessed from all pages without having to recreate the custom Drawer widget in every page.

Why Persistent Drawer is Important

A persistent navigation drawer is essential in many apps as it provides a consistent user experience and makes it easier for users to navigate through the app. By having a persistent drawer, you can:

Provide a consistent navigation experience across all pages
Reduce the complexity of creating a custom Drawer widget for each page
Improve the overall user experience of your app

Creating a Persistent Drawer in Flutter

To create a persistent drawer in Flutter, you can use the Drawer widget and wrap it with a Scaffold widget. However, to make it persistent across all pages, you need to create a custom Drawer widget and use it throughout your app.

Here's an example of how you can create a custom Drawer widget:

import 'package:flutter/material.dart';
class CustomDrawer extends StatelessWidget 
@override
Widget build(BuildContext context) {
return Drawer(
child ListView(
children: [
DrawerHeader(
decoration: BoxDecoration(
color: Colors.blue,
),
child: Text(
'Custom Drawer',
style: TextStyle(
color: Colors.white,
fontSize: 24,
),
),
),
ListTile(
title: Text('Page 1'),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => Page1()),
);
,
),
ListTile(
title: Text('Page 2'),
onTap: () 
Navigator.push(
context,
MaterialPageRoute(builder (context) => Page2()),
);
,
),
],
),
);
}
}

Using the Custom Drawer in a Scaffold

To use the custom Drawer in a Scaffold, you need to wrap the Scaffold with a MaterialApp widget and use the drawer property to specify the custom Drawer widget.

Here's an example of how you can use the custom Drawer in a Scaffold:

import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget 
@override
Widget build(BuildContext context) {
return MaterialApp(
title 'Persistent Drawer Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(),
);

}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> 
@override
Widget build(BuildContext context) {
return Scaffold(
appBar AppBar(
title: Text('Persistent Drawer Demo'),
),
drawer: CustomDrawer(),
body: Center(
child: Text('This is the home page'),
),
);

}

Navigating to Other Pages

To navigate to other pages from the custom Drawer, you can use the Navigator.push method to push a new route onto the navigator.

Here's an example of how you can navigate to other pages from the custom Drawer:

import 'package:flutter/material.dart';
class CustomDrawer extends StatelessWidget 
@override
Widget build(BuildContext context) {
return Drawer(
child ListView(
children: [
DrawerHeader(
decoration: BoxDecoration(
color: Colors.blue,
),
child: Text(
'Custom Drawer',
style: TextStyle(
color: Colors.white,
fontSize: 24,
),
),
),
ListTile(
title: Text('Page 1'),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => Page1()),
);
,
),
ListTile(
title: Text('Page 2'),
onTap: () 
Navigator.push(
context,
MaterialPageRoute(builder (context) => Page2()),
);
,
),
],
),
);
}
}
