FlutterDev：系统菜单栏

保留部分原生菜单

添加插件

使用我修改过的插件，该插件能够保留window、help两个Mac原生菜单。

macos_menu:
  git:
    url: https://github.com/SX-Code/macos_menu.git
    ref: main

插件原作者: https://github.com/intonarumori/macos_menu.git

使用插件

1、生成自定义的菜单

// 枚举，便于循环
enum VideoClass {
  home('首页'),
  movie("电影"),
  skits("短剧"),
  drama("电视剧"),
  anime("动漫"),
  documentary("综艺"),
  variety("纪录片");
  const VideoClass(this.name);
  final String name;
}
// 生成自定义菜单，并绑定快捷按键
List<MacosMenuItem> _buildMenuItem() {
  List<MacosMenuItem> res = [];
  List<VideoClass> enums = VideoClass.values;
  int i = 0;
  for (i = 0; i < enums.length; i++) {
    int index = i; // 需要这样写
    res.add(
      MacosMenuItem(
        label: enums[i].name,
        shortcut: CharacterActivator('$index', meta: true),
        onSelected: () {
          // 使用Provider跳转指定的页面
          Provider.of<RootProvider>(
            NavigatorProvider.navigatorKey.currentState!.context,
            listen: false,
          ).index = index;
        },
      ),
    );
  }
  res.add(MacosMenuItem(
    label: "片单",
    shortcut: CharacterActivator('${i + 1}', meta: true),
    onSelected: () {
      Provider.of<RootProvider>(
        NavigatorProvider.navigatorKey.currentState!.context,
        listen: false,
      ).index = i;
    },
  ));
  return res;
}

2、定义顶级菜单选项

List<MacosMenuItem> _buildTopLevelMenus() {
  return [
    MacosMenu(label: "Main", menus: [
      MacosMenuItemGroup(members: [
        if (MacosPlatformProvidedMenuItem.hasMenu(
            MacosPlatformProvidedMenuItemType.about)) ...[
          const MacosPlatformProvidedMenuItem(
              type: MacosPlatformProvidedMenuItemType.about)
        ],
      ]),
      MacosMenuItem(
        label: "设置",
        onSelected: () {
          Provider.of<RootProvider>(
            NavigatorProvider.navigatorKey.currentState!.context,
            listen: false,
          ).index = 8;
        },
      ),
      MacosMenuItemGroup(members: [
        if (MacosPlatformProvidedMenuItem.hasMenu(
            MacosPlatformProvidedMenuItemType.servicesSubmenu)) ...[
          const MacosPlatformProvidedMenuItem(
              type: MacosPlatformProvidedMenuItemType.servicesSubmenu)
        ],
      ]),
      if (MacosPlatformProvidedMenuItem.hasMenu(
          MacosPlatformProvidedMenuItemType.quit)) ...[
        const MacosPlatformProvidedMenuItem(
            type: MacosPlatformProvidedMenuItemType.quit)
      ],
    ]),
    // 自定义菜单项
    MacosMenu(label: "影视", menus: _buildMenuItem()),
  ];
}

3、定义帮助菜单选项

var helpItems = [
  MacosMenuItem(
    label: 'Visit Website',
    shortcut: const CharacterActivator("w", meta: true),
    onSelected: () {},
  ),
];

4、设置菜单

void main(List<String> args) async {
  WidgetsFlutterBinding.ensureInitialized();
  // 设置菜单项, 只针对MacOS
  MacosMenuBinding.instance.delegate.setMenus(_buildTopLevelMenus(), helpItems);
  runApp(child: const MyApp());
}

代码解释

下面的代码中使用了插件provider，其属性index绑定了stack的 index 属性，当给index赋值时，会通知 stack 切换页面。

class RootProvider extends ChangeNotifier {
int _index = 0;

int get index => _index;

set index(int index) {
 _index = index;
 notifyListeners(); // 通知组件更新
}
}

NavigatorProvider.navigatorKey.currentState!.context，该context在此刻并未被赋值，当页面出现时，才会被赋值。

MaterialApp(
navigatorKey: NavigatorProvider.navigatorKey,
)

Provider.of<RootProvider>(
  NavigatorProvider.navigatorKey.currentState!.context,
  listen: false,
).index = 8;

菜单汉化

使用Xcode打开项目中的macos，在Runner->Info->Localozations中添加简体中文汉化，会帮我们生成汉化文件。

打开生成的文件：macos/Runner/zh-Hans.lproj/MainMenu.strings，根据需要汉化内容，案例如下：

/* Class = "NSMenuItem"; title = "APP_NAME"; ObjectID = "1Xt-HY-uBw"; */
"1Xt-HY-uBw.title" = "APP_NAME";
