An advanced drawer widget, that can be fully customized with size, text, color, and radius of corners. A sample video is given below to get an idea about what we are going to do in this article.
Step By Step Implementation
Step 1: Create a New Project in Android Studio
To set up Flutter Development on Android Studio please refer to Android Studio Setup for Flutter Development, and then create a new project in Android Studio please refer to Creating a Simple Application in Flutter.
Step 2: Import the package into the main file
import 'package:flutter/cupertino.dart'; import 'package:flutter/material.dart';
Code Example
Dart
// ignore_for_file: prefer_const_constructorsimport 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}class MyApp extends StatelessWidget {
const MyApp({super.key});
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Advanced Drawer',
theme: ThemeData(
// This is the theme of your application.
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
primarySwatch: Colors.green,
),
home: AdvancedDrawer(),
);
}
}class AdvancedDrawer extends StatefulWidget {
const AdvancedDrawer({super.key});
@override
State<AdvancedDrawer> createState() => _AdvancedDrawerState();

Code Explanation
- Here we first make the project and remove the default code and give the AdvancedDrawer in home and make the Stateful widget and give the AdvancedDrawer class name of the stateful widget.
- Now return the scaffold in the stateful widget. In the stateful widget, we are taking the AppBar, and the drawer, and write the text widget in the body.
- Now in drawer class, we take the Column in the column we take the children and in children, we take the circle avatar and all the columns wrap with the singlechildscrollview.
- Now in the row, we take the icon widget and the text widget and give the sized box in between both widgets.
- For making the dropdown we take the expansion tile and in init, we do all things in the child.
- For making it clickable we wrap it with the gesture detector and in the gesture detector, we give the on-tap function also we are giving it in our code you just comment out and give the location of your page.
