Flutter桌面软件开发中使用window_manager自定义关闭、最大化 最小化按钮

Flutter中使用window_manager自定义关闭按钮

一、Flutter中使用window_manager自定义关闭按钮 初始化配置

import '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());
}

二、window_manager自定义关闭、最大化 最小化按钮

import 'package:window_manager/window_manager.dart';
import 'package:flutter/material.dart';

class WindowButtons extends StatefulWidget {
  const WindowButtons({Key? key}) : super(key: key);
  @override
  _WindowButtonsState createState() => _WindowButtonsState();
}


class _WindowButtonsState extends State<WindowButtons> {
  @override
  Widget build(BuildContext context) {
    return const SizedBox(
      width: 138,
      height: 50,
      child: WindowCaption(
        brightness: Brightness.light,
        backgroundColor: Colors.transparent,
      ),
    );
    
  }
}

三、调用

 appBar: AppBar(
        toolbarHeight: 30,
        title: const DragToMoveArea(
          child: SizedBox(
            height: 40,
            width: double.infinity,
          ),
        ),
        actions: [if (Platform.isWindows == true) const WindowButtons()],
      ),
