  WindowOptions windowOptions = const WindowOptions(

  await initSystemTray();

  runApp(const MyApp());
}

flutter桌面端托盘采用system_tray组件。

// 初始化系统托盘图标
Future<void> initSystemTray() async {
  String trayIco = 'assets/images/tray.ico';
  SystemTray systemTray = SystemTray();

  // 初始化系统托盘
  await systemTray.initSystemTray(
    title: 'Flutter-MacOS',
    iconPath: trayIco,
  );

  // 右键菜单
  final Menu menu = Menu();
  await menu.buildFrom([
    MenuItemLabel(label: '打开主界面', image: 'assets/images/tray_main.bmp', onClicked: (menuItem) async => await windowManager.show()),
    MenuItemLabel(label: '隐藏窗口', image: 'assets/images/tray_hide.bmp', onClicked: (menuItem) async => await windowManager.hide()),
    MenuItemLabel(label: '设置中心', image: 'assets/images/tray_setting.bmp', onClicked: (menuItem) => {}),
    MenuItemLabel(label: '锁屏', image: 'assets/images/tray_lock.bmp', onClicked: (menuItem) => {}),
    MenuItemLabel(label: '关闭程序并退出', image: 'assets/images/tray_logout.bmp', onClicked: (menuItem) async => await windowManager.destroy()),
  ]);
  await systemTray.setContextMenu(menu);

  // 右键事件
  systemTray.registerSystemTrayEventHandler((eventName) async {
    debugPrint('eventName: $eventName');
    if (eventName == kSystemTrayEventClick) {
      Platform.isWindows ? await windowManager.show() : systemTray.popUpContextMenu();
    } else if (eventName == kSystemTrayEventRightClick) {
      Platform.isWindows ? systemTray.popUpContextMenu() : await windowManager.show();
    }
  });
}

flutter窗口管理window_manager

flutter-macos项目采用window_manager插件进行窗口管理。

有下面几个组件是文档没有写的：

  • DragToMoveArea 拖拽窗口
  • DragToResizeArea 缩放窗口
  • VirtualWindowFrame（仅Linux）
  • WindowCaption 自定义顶部导航栏
  • WindowCaptionButtonIcon 导航栏右上角按钮组

顶部导航栏及右上角最小化/最大化/关闭按钮采用自定义组件实现功能。

return Container(
  height: widget.titlebarHeight,
  decoration: BoxDecoration(
    backgroundBlendMode: widget.backgroundBlendMode,
    color: widget.backgroundColor,
    gradient: widget.gradient,
  ),
  child: Stack(
    children: [
      Row(
        children: [
          // 头部
          Container(
            child: widget.leading,
          ),
          // 可拖动区(标题)
          Expanded(
            child: DragToMoveArea(
              child: SizedBox(
                height: double.infinity,
                child: Row(
                  children: [
                    // 标题(不居中)
                    customTitle(!widget.centerTitle),
                  ],
                ),
              ),
            ),
          ),
          // 尾部
          Container(
            child: widget.trailing,
          ),
          // 按钮组
          WinBtns(theme: widget.actionButtonTheme, buttonSize: widget.actionButtonSize),
        ],
      ),
      // 标题(居中)
      customTitle(widget.centerTitle),
    ],
  ),
);

flutter3桌面布局

如上图：整体采用顶部自定义导航条+桌面菜单栏+dock菜单三大模块。

/*

return Scaffold(
  key: scaffoldKey,
  body: Container(
    // 背景图主题
    decoration: skinTheme(),
    // DragToResizeArea自定义缩放窗口
    child: DragToResizeArea(
      child: Flex(
        direction: Axis.vertical,
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          // 导航栏
          WindowTitlebar(
            onDrawer: () {
              // 自定义打开右侧drawer
              scaffoldKey.currentState?.openEndDrawer();
            },
          ),

          // 桌面区域
          Expanded(
            child: GestureDetector(
              child: Container(
                color: Colors.transparent,
                child: Row(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    Expanded(
                      child: GestureDetector(
                        child: const WindowDesktop(),
                        onSecondaryTapDown: (TapDownDetails details) {
                          posDX = details.globalPosition.dx;
                          posDY = details.globalPosition.dy;
                        },
                        onSecondaryTap: () {
                          debugPrint('桌面图标右键');
                          showDeskIconContextmenu();
                        },
                      ),
                    ),
                  ],
                ),
              ),
              onSecondaryTapDown: (TapDownDetails details) {
                posDX = details.globalPosition.dx;
                posDY = details.globalPosition.dy;
              },
              onSecondaryTap: () {
                debugPrint('桌面右键');
                showDeskContextmenu();
              },
            ),
          ),

          // Dock菜单
          settingController.settingData['dock'] == 'windows' ?
          const WindowTabbar()
          :
          const WindowDock()
          ,
        ],
      ),
    ),
  ),
  endDrawer: Drawer(
    shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(0.0)),
    width: 300,
    child: const Settings(),
  ),
);

flutter实现dock菜单

采用毛玻璃虚化背景、支持拖拽排序和二级弹窗菜单。支持mac和windows11两种风格。

MouseRegion(
  cursor: SystemMouseCursors.click,
  onEnter: (event) {
    setState(() {
      hoveredIndex = index;
    });
    controller.forward(from: 0.0);
  },
  onExit: (event) {
    setState(() {
      hoveredIndex = -1;
    });
    controller.stop();
  },
  child: GestureDetector(
    onTapDown: (TapDownDetails details) {
      anchorDx = details.globalPosition.dx;
    },
    onTap: () {
      if(item!['children'] != null) {
        showDockDialog(item!['children']);
      }
    },
    // 缩放动画
    child: ScaleTransition(
      alignment: Alignment.bottomCenter,
      scale: hoveredIndex == index ? 
      controller.drive(Tween(begin: 1.0, end: 1.5).chain(CurveTween(curve: Curves.easeOutCubic)))
      :
      Tween(begin: 1.0, end: 1.0).animate(controller)
      ,
      child: UnconstrainedBox(
        child: Stack(
          alignment: AlignmentDirectional.topCenter,
          children: [
            // tooltip提示
            Visibility(
              visible: hoveredIndex == index && !draggable,
              child: Positioned(
                top: 0,
                child: SizedOverflowBox(
                  size: Size.zero,
                  child: Container(
                    alignment: Alignment.center,
                    padding: const EdgeInsets.symmetric(horizontal: 8.0, vertical: 1.0),
                    margin: const EdgeInsets.only(bottom: 20.0),
                    decoration: BoxDecoration(
                      color: Colors.black54,
                      borderRadius: BorderRadius.circular(3.0),
                    ),
                    child: Text('${item!['tooltip']}', style: const TextStyle(color: Colors.white, fontSize: 8.0, fontFamily: 'arial')),
                  ),
                ),
              ),
            ),
            // 图片/图标
            item!['children'] != null ?
            thumbDock(item!['children'])
            :
            SizedBox(
              height: 35.0,
              width: 35.0,
              child: item!['type'] != null && item!['type'] == 'icon' ? 
              IconTheme(
                data: const IconThemeData(color: Colors.white, size: 32.0),
                child: item!['imgico'],
              )
              :
              Image.asset('${item!['imgico']}')
              ,
            ),
            // 圆点
            Visibility(
              visible: item!['active'] != null,
              child: Positioned(
                bottom: 0,
                child: SizedOverflowBox(
                  size: Size.zero,
                  child: Container(
                    margin: const EdgeInsets.only(top: 2.0),
                    height: 4.0,
                    width: 4.0,
                    decoration: BoxDecoration(
                      color: Colors.black87,
                      borderRadius: BorderRadius.circular(10.0),
                    ),
                  ),
                ),
              ),
            ),
          ],
        ),
      ),
    ),
  ),
)

支持如下json格式配置。

List dockList = [
