如何在 Flutter 应用程序中添加桌面版网站？

Question

我需要在我的应用程序中显示网站的桌面版本。对我来说，它显示了应用程序的移动版本：

代码：

import 'package:flutter/material.dart';
import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';
import './landing_page.dart';

class ComicsPage extends StatefulWidget {

@override
_ComicsPageState createState() => _ComicsPageState();

 }
class _ComicsPageState extends State<ComicsPage> {
TextEditingController controller = TextEditingController();
FlutterWebviewPlugin flutterWebviewPlugin = FlutterWebviewPlugin();
var urlString = "https://avengers.marvelhq.com/comics";

 launchUrl() {
 setState(() {
  urlString = controller.text;
  flutterWebviewPlugin.reloadUrl(urlString);
 });
}

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

flutterWebviewPlugin.onStateChanged.listen((WebViewStateChanged wvs) {
  print(wvs.type);
 });
 }

@override
Widget build(BuildContext context) {
 String newUA= "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 
 Firefox/40.1";
 return WebviewScaffold(
  appBar: AppBar(
    actions: <Widget>[
      IconButton(
        icon: Icon(Icons.cancel,size: 45.0),
        onPressed: () => Navigator.of(context).pushAndRemoveUntil(new 
    MaterialPageRoute(builder: (BuildContext context) => new LandingPage()), 
   (Route route) => route == null),
      )
    ],
    title: const Text('Marvel Comics'),
  ),
  url: urlString,
  withZoom: true,
  withJavascript: true,
  withLocalStorage: true,
  scrollBar: true,
  enableAppScheme: true,

  userAgent: newUA,
  clearCookies: false,
  clearCache: false,

   );
 }
}

我需要像这个示例图像一样查看

特别是对于这个网站：点击这里

我试图将用户代理更改为桌面版本（Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.1）。它不起作用..给我解决方案。

Answer 1

我知道这个迟到的答案，但也许有人会需要它

顺便说一句，我之前在颤振中也遇到过这个问题

做了这个技巧后，它对我有用

只需在页面加载后尝试评估此代码 JavaScript

像这样

//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,
    );
  }
