What is Flutter Popup Menu Icon Size?
Flutter popup menu icon size is the size of the icon of the Flutter popup menu button. In this post, we will also see what the default Flutter popup menu icon size is and how we will change it. So let’s get right into explaining how to change Flutter popup menu icon size.
Default Flutter Popup Menu Icon Size
To see the default Flutter popup menu icon size, we have to define the Flutter popup menu button widget, we also have given it one Flutter popup menu item so when we tap on the Flutter popup menu icon then it will show a Flutter popup menu icon with one item. We have defined Flutter popup menu icon inside the actions constructor of the Flutter appbar widget. See the below code:
PopupMenuButton( onSelected: (value) {}, itemBuilder: (context) { return [ PopupMenuItem( padding: EdgeInsets.only(right: 50, left: 20), value: 'Home', child: Text( 'Home', style: TextStyle( color: Colors.green, fontSize: 13, fontWeight: FontWeight.w500), )), ]; }, )
As you can see in the above image, this is the default Flutter popup menu icon size. Now let’s see how we can change the size of the Flutter popup menu icon.
Change Flutter Popup Menu Icon Size
To change the Flutter popup menu icon size, we have to use the icon size constructor of the Flutter popup menu button widget class. It takes a double value. For demonstration, we have passed it a greater value to show that the size of the icon changes with it. See the below code:
iconSize: 30

Custom Flutter Popup Menu Design Source Code
import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: Homepage(), ); } } class Homepage extends StatefulWidget { @override State<Homepage> createState() => _HomepageState(); } class _HomepageState extends State<Homepage> { @override Widget build(BuildContext context) { return SafeArea( child: Scaffold( appBar: AppBar( toolbarHeight: 80, elevation: 0, backgroundColor: Colors.transparent, actions: [ PopupMenuButton( iconSize: 40, icon: Icon( Icons.more_vert, color: Colors.purple, ), elevation: 10, color: Colors.grey.shade100, onSelected: (value) { ScaffoldMessenger.of(context) .showSnackBar(SnackBar(content: Text('$value item pressed'))); }, itemBuilder: (context) { return [ PopupMenuItem( padding: EdgeInsets.only(right: 50, left: 20), value: 'Home', child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ Row( children: [ Icon( Icons.home, size: 20, color: Colors.purple, ), SizedBox( width: 5, ), Text( 'Home', style: TextStyle( color: Colors.purple, fontSize: 13, fontWeight: FontWeight.w500), ), ], ), Divider() ], )), PopupMenuItem( padding: EdgeInsets.only(right: 50, left: 20), value: 'Chats', child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ Row( children: [ Icon( Icons.chat, size: 20, color: Colors.purple, ), SizedBox( width: 5, ), Text( 'Chats', style: TextStyle( color: Colors.purple, fontSize: 13, fontWeight: FontWeight.w500), ), ], ), Divider() ], )), PopupMenuItem( padding: EdgeInsets.only(right: 50, left: 20), value: 'Sign out', child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ Row( children: [ Icon( Icons.logout, size: 20, color: Colors.purple, ), SizedBox( width: 5, ), Text( 'Sign out', style: TextStyle( color: Colors.purple, fontSize: 13, fontWeight: FontWeight.w500), ), ], ), Divider() ], )), ]; }, ) ], ), )); } }
