Question

我需要在我的应用中显示网站的桌面版本。对我来说，它显示了该应用的移动版本：

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,

   );
 }
}

i need to view like this sample image

尤其是对于此站点：click here

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

我知道这个较晚的答案，但也许有人会需要它

顺便说一句，我在扑扑之前也面临这个问题

完成这个技巧后，对我来说是有用的

只要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,
    );
  }

将用户代理参数从null更改为下面提到的值

WebView(
              userAgent: "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/20100101 Firefox/4.0",
              initialUrl: html,
              javascriptMode: JavascriptMode.unrestricted,
              onWebViewCreated: (WebViewController webViewController) {
                _controller.complete(webViewController);
              },
