Description:

menu bar

A customizable application menu bar with submenus for your Flutter Desktop apps.
The menu bar is rendered inside your Flutter app (i.e. not as a native menu bar like in macOS). Native menu bars (at least for macOS) are since lately supported by Flutter. In the future, a native option in this package could get added.

Usage #
First, download and import the package:
import 'package:menu_bar/menu_bar.dart';
copied to clipboard
1. Integrate the menu bar #
Wrap your application around the MenuBarWidget widget and add an empty list to barButtons so that you have assigned the 2 necessary fields. The child is your application under the menu bar:
MenuBarWidget(
barButtons: [],
child: Scaffold(...),
),
copied to clipboard
You should now see an empty menu bar above your application (see picture below). To add buttons with menus, proceed to step 2.

2. Create your menus #
To add buttons with menus, use the following widget structure:
MenuBarWidget
BarButton
SubMenu
MenuButton
MenuButton
...
BarButton
SubMenu
MenuButton
MenuButton
...
copied to clipboard
In this example, we will add the following menu bar:

MenuBarWidget(
// The buttons in this List are displayed as the buttons on the bar itself
barButtons: [
BarButton(
text: const Text('File', style: TextStyle(color: Colors.white)),
submenu: SubMenu(
menuItems: [
MenuButton(
text: const Text('Save'),
onTap: () {},
icon: const Icon(Icons.save),
shortcutText: 'Ctrl+S',
),
const MenuDivider(),
MenuButton(
text: const Text('Exit'),
onTap: () {},
icon: const Icon(Icons.exit_to_app),
shortcutText: 'Ctrl+Q',
),
],
),
),
BarButton(
text: const Text('Help', style: TextStyle(color: Colors.white)),
submenu: SubMenu(
menuItems: [
MenuButton(
text: const Text('View License'),
onTap: () {},
),
MenuButton(
text: const Text('About'),
onTap: () {},
icon: const Icon(Icons.info),
),
],
),
),
],

// Set the child, i.e. the application under the menu bar
child: Scaffold(...),
),
copied to clipboard
