return true + return false } } ``` #### 关闭前确认 ```dart import 'package:flutter/cupertino.dart'; import 'package:window_manager/window_manager.dart'; class HomePage extends StatefulWidget { @override _HomePageState createState() => _HomePageState(); } class _HomePageState extends State with WindowListener { @override void initState() { super.initState(); windowManager.addListener(this); _init(); } @override void dispose() { windowManager.removeListener(this); super.dispose(); } void _init() async { // 添加此行以覆盖默认关闭处理程序 await windowManager.setPreventClose(true); setState(() {}); } @override Widget build(BuildContext context) { // ... } @override void onWindowClose() async { bool _isPreventClose = await windowManager.isPreventClose(); if (_isPreventClose) { showDialog( context: context, builder: (_) { return AlertDialog( title: Text('Are you sure you want to close this window?'), actions: [ TextButton( child: Text('No'), onPressed: () { Navigator.of(context).pop(); }, ), TextButton( child: Text('Yes'), onPressed: () { Navigator.of(context).pop(); await windowManager.destroy(); }, ), ], ); }, ); } } } ``` #### 在启动时隐藏 ##### Linux 更改文件 `linux/my_application.cc` 如下： ```diff ... // Implements GApplication::activate. static void my_application_activate(GApplication* application) { ... gtk_window_set_default_size(window, 1280, 720); - gtk_widget_show(GTK_WIDGET(window)); + gtk_widget_realize(GTK_WIDGET(window)); g_autoptr(FlDartProject) project = fl_dart_project_new(); fl_dart_project_set_dart_entrypoint_arguments(project, self->dart_entrypoint_arguments); FlView* view = fl_view_new(project); gtk_widget_show(GTK_WIDGET(view)); gtk_container_add(GTK_CONTAINER(window), GTK_WIDGET(view)); fl_register_plugins(FL_PLUGIN_REGISTRY(view)); gtk_widget_grab_focus(GTK_WIDGET(view)); } ... ``` ##### macOS 更改文件 `macos/Runner/MainFlutterWindow.swift` 如下： ```diff import Cocoa import FlutterMacOS +import window_manager class MainFlutterWindow: NSWindow { override func awakeFromNib() { let flutterViewController = FlutterViewController.init() let windowFrame = self.frame self.contentViewController = flutterViewController self.setFrame(windowFrame, display: true) RegisterGeneratedPlugins(registry: flutterViewController) super.awakeFromNib() } + override public func order(_ place: NSWindow.OrderingMode, relativeTo otherWin: Int) { + super.order(place, relativeTo: otherWin) + hiddenWindowAtLaunch() + } } ``` ##### Windows 更改文件 `windows/runner/win32_window.cpp` 如下： ```diff bool Win32Window::CreateAndShow(const std::wstring& title, const Point& origin, const Size& size) { ... HWND window = CreateWindow( - window_class, title.c_str(), WS_OVERLAPPEDWINDOW | WS_VISIBLE, + window_class, title.c_str(), + WS_OVERLAPPEDWINDOW, // do not add WS_VISIBLE since the window will be shown later Scale(origin.x, scale_factor), Scale(origin.y, scale_factor), Scale(size.width, scale_factor), Scale(size.height, scale_factor), nullptr, nullptr, GetModuleHandle(nullptr), this); ``` 使用 flutter 3.7 创建的 Windows 项目 更改 `windows/runner/flutter_window.cpp` 如下: ```diff bool FlutterWindow::OnCreate() { ... flutter_controller_->engine()->SetNextFrameCallback([&]() { - this->Show(); + "" //删除 this->Show() }); ``` 确保在 `onWindowFocus` 事件中调用一次 `setState`。 ```dart import 'package:flutter/cupertino.dart'; import 'package:window_manager/window_manager.dart'; class HomePage extends StatefulWidget { @override _HomePageState createState() => _HomePageState(); } class _HomePageState extends State with WindowListener { @override void initState() { super.initState(); windowManager.addListener(this); } @override void dispose() { windowManager.removeListener(this); super.dispose(); } @override Widget build(BuildContext context) { // ... } @override void onWindowFocus() { // Make sure to call once. setState(() {}); // do something } } ``` ## 文章 - [关闭窗口后点击Dock图标进行恢复](https://leanflutter.org/zh/blog/click-dock-icon-to-restore-after-closing-the-window) - [让应用成为单实例](https://leanflutter.org/zh/blog/making-the-app-single-instanced) ## 谁在用使用它？ - [Airclap](https://airclap.app/) - 任何文件，任意设备，随意发送。简单好用的跨平台高速文件传输APP。 - [AuthPass](https://authpass.app/) - 基于Flutter的密码管理器，适用于所有平台。兼容Keepass 2.x（kdbx 3.x）。 - [Biyi (比译)](https://biyidev.com/) - 一个便捷的翻译和词典应用程序。 - [BlueBubbles](https://github.com/BlueBubblesApp/bluebubbles-app) - BlueBubbles is an ecosystem of apps bringing iMessage to Android, Windows, and Linux - [LunaSea](https://github.com/CometTools/LunaSea) - A self-hosted controller for mobile and macOS built using the Flutter framework. - [Linwood Butterfly](https://github.com/LinwoodCloud/Butterfly) - 用 Flutter 编写的开源笔记应用 - [RustDesk](https://github.com/rustdesk/rustdesk) - 远程桌面软件，开箱即用，无需任何配置。您完全掌控数据，不用担心安全问题。 - [Ubuntu Desktop Installer](https://github.com/canonical/ubuntu-desktop-installer) - This project is a modern implementation of the Ubuntu Desktop installer. - [UniControlHub](https://github.com/rohitsangwan01/uni_control_hub) - Seamlessly bridge your Desktop and Mobile devices ## API ### WindowManager #### Methods ##### waitUntilReadyToShow Wait until ready to show. ##### destroy Force closing the window. ##### close Try to close the window. ##### isPreventClose Check if is intercepting the native close signal. ##### setPreventClose Set if intercept the native close signal.
