the system is android 7.1 and above are my code

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


import '../common/model/Source.dart';


class WebResWidget extends StatefulWidget {
  Source source;
  Size size;

  WebResWidget({Key key, this.source, this.size}) : super(key: key);

  @override
  _WebResWidgetState createState() => _WebResWidgetState();
}

class _WebResWidgetState extends State<WebResWidget> {
  final flutterWebViewPlugin = FlutterWebviewPlugin();
 
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
  }

  @override
  void dispose() {
    // TODO: implement dispose
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return WebviewScaffold(url: 'http://192.168.1.58:8090/#/login');
  }
}
