将此添加到你的软件包的 pubspec.yaml 文件：
dependencies:
window_manager: ^0.2.8或
dependencies:
window_manager:
git:
url: https://github.com/leanflutter/window_manager.git
ref: mainimport 'package:flutter/material.dart';
import 'package:window_manager/window_manager.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
// 必须加上这一行。
await windowManager.ensureInitialized();
WindowOptions windowOptions = WindowOptions(
size: Size(800, 600),
center: true,
backgroundColor: Colors.transparent,
skipTaskbar: false,
titleBarStyle: TitleBarStyle.hidden,
);
windowManager.waitUntilReadyToShow(windowOptions, () async {
await windowManager.show();
await windowManager.focus();
});
runApp(MyApp());
}
请看这个插件的示例应用，以了解完整的例子。
import 'package:flutter/cupertino.dart';
import 'package:window_manager/window_manager.dart';
class HomePage extends StatefulWidget {
@override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> with WindowListener {
@override
void initState() {
windowManager.addListener(this);
super.initState();
}
@override
void dispose() {
windowManager.removeListener(this);
super.dispose();
}
@override
Widget build(BuildContext context) {
// ...
}
@override
void onWindowEvent(String eventName) {
print('[WindowManager] onWindowEvent: $eventName');
}
@override
void onWindowClose() {
// do something
}
@override
void onWindowFocus() {
// do something
}
@override
void onWindowBlur() {
// do something
}
@override
void onWindowMaximize() {
// do something
}
@override
void onWindowUnmaximize() {
// do something
}
@override
void onWindowMinimize() {
// do something
}
@override
void onWindowRestore() {
// do something
}
@override
void onWindowResize() {
// do something
}
@override
void onWindowMove() {
// do something
}
@override
void onWindowEnterFullScreen() {
// do something
}
@override
void onWindowLeaveFullScreen() {
// do something
}
}如果你需要使用 hide 方法，你需要禁用 QuitOnClose。
更改文件 macos/Runner/AppDelegate.swift 如下：
import Cocoa
import FlutterMacOS
@NSApplicationMain
class AppDelegate: FlutterAppDelegate {
override func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
- return true
+ return false
}
}import 'package:flutter/cupertino.dart';
import 'package:window_manager/window_manager.dart';
class HomePage extends StatefulWidget {
@override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> with WindowListener {
@override
void initState() {
windowManager.addListener(this);
_init();
super.initState();
}
@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();
},
),
],
);
},
);
}
}
}更改文件 linux/my_application.cc 如下：
...
// 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));
}
...
更改文件 macos/Runner/MainFlutterWindow.swift 如下：
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()
+ }
}
更改文件 windows/runner/win32_window.cpp 如下：
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);确保在 onWindowFocus 事件中调用一次 setState。

@override
_HomePageState createState() => _HomePageState();

@override
Widget build(BuildContext context) {

@override
void onWindowFocus() {
// Make sure to call once.
setState(() {});
