bitsdojo_window_windows_v3 是一个用于 Flutter 桌面应用程序的插件，特别是针对 Windows 平台的窗口管理。它允许你自定义窗口的标题栏、窗口边框、窗口大小等。以下是如何使用 bitsdojo_window_windows_v3 插件的基本步骤：

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 bitsdojo_window_windows_v3 插件的依赖。

dependencies:
  flutter:
    sdk: flutter
  bitsdojo_window_windows_v3: ^3.0.0+1

然后运行 flutter pub get 来获取依赖。

2. 初始化插件

在你的 main.dart 文件中，初始化 bitsdojo_window 插件。

import 'package:flutter/material.dart';
import 'package:bitsdojo_window_windows_v3/bitsdojo_window_windows.dart';

void main() {
  runApp(MyApp());
  doWhenWindowReady(() {
    final win = appWindow;
    win.minSize = Size(400, 300);
    win.size = Size(800, 600);
    win.alignment = Alignment.center;
    win.title = "My Flutter App";
    win.show();
  });
}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Demo Home Page'),
      ),
      body: Center(
        child: Text('Hello, world!'),
      ),
    );
  }
}

3. 自定义窗口标题栏

bitsdojo_window_windows_v3 允许你自定义窗口的标题栏。你可以使用 WindowTitleBarBox 来创建自定义的标题栏。

import 'package:flutter/material.dart';
import 'package:bitsdojo_window_windows_v3/bitsdojo_window_windows.dart';

void main() {
  runApp(MyApp());
  doWhenWindowReady(() {
    final win = appWindow;
    win.minSize = Size(400, 300);
    win.size = Size(800, 600);
    win.alignment = Alignment.center;
    win.title = "My Flutter App";
    win.show();
  });
}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: WindowTitleBarBox(
          child: Row(
            children: [
              Expanded(child: MoveWindow()),
              WindowButtons(),
            ],
          ),
        ),
      ),
      body: Center(
        child: Text('Hello, world!'),
      ),
    );
  }
}

class WindowButtons extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Row(
      children: [
        MinimizeWindowButton(),
        MaximizeWindowButton(),
        CloseWindowButton(),
      ],
    );
  }
}

4. 窗口控制

bitsdojo_window_windows_v3 提供了多种方法来控制窗口的行为，例如最小化、最大化、关闭窗口等。

• appWindow.minimize()：最小化窗口。
• appWindow.maximize()：最大化窗口。
• appWindow.restore()：恢复窗口到之前的大小。
• appWindow.close()：关闭窗口。

你可以在按钮的 onPressed 事件中调用这些方法。

class WindowButtons extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Row(
      children: [
        IconButton(
          icon: Icon(Icons.minimize),
          onPressed: () => appWindow.minimize(),
        ),
        IconButton(
          icon: Icon(Icons.crop_square),
          onPressed: () => appWindow.maximize(),
        ),
        IconButton(
          icon: Icon(Icons.close),
          onPressed: () => appWindow.close(),
        ),
      ],
    );
  }
}
