(摘) Flutter 自定义窗口 bitsdojo

其实还不能完全算是自定义窗口。比如异形窗口就没有解决。
bitsdojo_window 是一个用来定制桌面端窗口的插件

pubspec.yaml: bitsdojo_window: ^last_version
Windows下的应用：打开 windows\runner\main.cpp 文件，添加以下代码到前面：

#include <bitsdojo_window_windows/bitsdojo_window_plugin.h>
auto bdw = bitsdojo_window_configure(BDW_CUSTOM_FRAME | BDW_HIDE_ON_STARTUP);

以下示例被我修改过

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

void main() {
  runApp(const MyApp());
  doWhenWindowReady(() {
    final win = appWindow;
    const initialSize = Size(600, 450);
    win.minSize = initialSize;
    win.size = initialSize;
    win.title = "可以自定义的窗口";
    win.alignment = Alignment.center;
    win.show();
  });
}

const borderColor = Color.fromARGB(255, 31, 21, 3);

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: WindowBorder(
          color: borderColor,
          width: 1,
          child: Row(
            children: const [RightSide()],
          ),
        ),
      ),
    );
  }
}

const backgroundStartColor = Color.fromARGB(255, 235, 234, 229);
const backgroundEndColor = Color.fromARGB(255, 196, 184, 164);

class RightSide extends StatelessWidget {
  const RightSide({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Expanded(
      child: Container(
        decoration: const BoxDecoration(
          gradient: LinearGradient(
              begin: Alignment.topCenter,
              end: Alignment.bottomCenter,
              colors: [backgroundStartColor, backgroundEndColor],
              stops: [0.0, 1.0]),
        ),
        child: Column(children: [
          WindowTitleBarBox(
            child: Row(
              children: [Expanded(child: MoveWindow()), const WindowButtons()],
            ),
          )
        ]),
      ),
    );
  }
}

final buttonColors = WindowButtonColors(
    iconNormal: const Color(0xFF805306), // 常态颜色
    mouseOver: const Color(0xFFF6A00C), // 鼠标移入颜色
    mouseDown: const Color(0xFF805306), // 鼠标按下颜色
    iconMouseOver: const Color(0xFF805306),
    iconMouseDown: const Color(0xFFFFD500));

final closeButtonColors = WindowButtonColors(
    mouseOver: const Color(0xFFD32F2F),
    mouseDown: const Color(0xFFB71C1C),
    iconNormal: const Color(0xFF805306),
    iconMouseOver: Colors.white);

class WindowButtons extends StatefulWidget {
  const WindowButtons({Key? key}) : super(key: key);

  @override
  _WindowButtonsState createState() => _WindowButtonsState();
}

class _WindowButtonsState extends State<WindowButtons> {
  void maximizeOrRestore() {
    setState(() {
      appWindow.maximizeOrRestore();
    });
  }

  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        MinimizeWindowButton(colors: buttonColors),
        appWindow.isMaximized
            ? RestoreWindowButton(
                colors: buttonColors,
                onPressed: maximizeOrRestore,
              )
            : MaximizeWindowButton(
                colors: buttonColors,
                onPressed: maximizeOrRestore,
              ),
        CloseWindowButton(colors: closeButtonColors),
      ],
    );
  }
}
