pubspec.yaml中引入依赖

dependencies:
  flutter:
    sdk: flutter
    
  cupertino_icons: ^0.1.2
  flutter_webview_plugin: ^0.3.4

main.dart中代码

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return WebviewScaffold(
      url: 'https://m.ctrip.com/html5/you/around',
      appBar: AppBar(
        title: Text(

      withZoom: true,
      withLocalStorage: true,

  }
}

android项目中已经修改配置文件兼容androidX,Webview打开https://www.baidu.com没有问题，但是打开localNavList中url的时候应用闪退，错误日志如下：
