macos_webview_kit 0.0.2+2

兼容MacOS系统的WebView插件，可以像在iOS系统上使用WKWebView一样丝滑。在Flutter MacOS项目中，通过chanel通道，实现WebView的打开（传递url）和关闭。

  final _macosWebviewKitPlugin = MacosWebviewKit();

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    // We also handle the message potentially returning null.
    try {
      platformVersion =
          await _macosWebviewKitPlugin.getPlatformVersion() ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  Future<void> openWebView1() async {
    await _macosWebviewKitPlugin.openWebView(urlString: "https://www.sohu.com");

  Future<void> closeWebView() async {
    await _macosWebviewKitPlugin.closeWebView();
  }

      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Column(
            children: [
              Text('Running on: $_platformVersion\n'),
