title: How to fix 'net::ERR_CLEARTEXT_NOT_PERMITTED' in flutter
body: <p>I have implemented webView in flutter but it is not opening my php website which is on server what I'm doing wrong.</p>
  
  <p>I am new to flutter and tried webview to integrate my website webpage in my application but no luck.</p>
  
  <pre><code>Widget build(BuildContext context) {
      // TODO: implement build
      return WebviewScaffold(
        appBar: AppBar(iconTheme:IconThemeData(color: Colors.white),title: Text("Intake Form",style:new TextStyle(color: Colors.white,fontWeight: FontWeight.bold)),backgroundColor:Colors.indigoAccent,automaticallyImplyLeading: false),
       url: url,
        //url: "http://xxxxxxxx/",
         withJavascript: true,
         supportMultipleWindows: true,
        withLocalStorage: true,
        allowFileURLs: true,
        enableAppScheme: true,
        appCacheEnabled: true,
        hidden: false,
        scrollBar: true,
        geolocationEnabled: false,
        clearCookies: true,
         // usesCleartextTraffic="true"
  
  
  
      );
    }
  </code></pre>
  
  <p>I expect the output as running webview but error is thrown.</p>
