i know this late answer but maybe someone will need it

BTW i also face this problem before in flutter

after do this trick it was work for me

just try eval this code JavaScript after your page is Loaded

like this

//to load desktop mode
  String js =
      "document.querySelector('meta[name=\"viewport\"]').setAttribute('content', 'width=1024px, initial-scale=' + (document.documentElement.clientWidth / 1024));";

  @override
  Widget build(BuildContext context) {
    final flutterWebViewPlugin = new FlutterWebviewPlugin();

    flutterWebViewPlugin.onProgressChanged.listen((event) {
      debugPrint("Progress $event");

        //this will make show in desktop mode 
        flutterWebViewPlugin.evalJavascript(js);

    });

    return WebviewScaffold(
      appBar: AppBar(
        title: Text("Desktop Mode"),
      ),
      url: "My Url",
      withJavascript: true,
      useWideViewPort: true,
      displayZoomControls: false,
      scrollBar: true,
      withZoom: true,
    );
  }
