title: how to get html content form flutterWebViewPlugin ( webview ) in flutter
body: <p>My question is pretty simple. how can I get the html data form the loaded page in webview. The data is in JSON format. for a reason I cannot use a post request for any get request here so I need to get the data with webview only. how to achive this ?</p>
  
  <pre><code>flutterWebViewPlugin.onUrlChanged.listen((String url) {
        if (url.contains('/recon?')) {
          print('printing url : $url');
          // need to get data ( html content ) on this url
          flutterWebViewPlugin.close();
          Navigator.of(context).pop(url);
        }
      });
  });
