Question

我创建了我的第一个Flutter模块，其中包含单个Web视图。独立运行模块或运行.ios / Runner项目时，其工作正常但是，当我将此模块与ios应用程序集成并运行该应用程序时，Web视图便消失了。

dart文件代码：

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:webview_flutter/webview_flutter.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Material App',
      theme: ThemeData.light(),
      home: Home(),
    );
  }
}

// ignore: must_be_immutable
class Home extends StatelessWidget {
  String _url = "https://www.google.com";
  final _key = UniqueKey();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
            title: Text("Web Viewwww"),
            leading: IconButton(
              icon: Icon(Icons.arrow_back),
              onPressed: () => SystemNavigator.pop(
                  animated: true) /*Navigator.pop(context, true)*/,
            )),
        body: Column(
          children: [
            Expanded(
                child: WebView(
                    key: _key,
                    javascriptMode: JavascriptMode.unrestricted,
                    initialUrl: _url))
          ],
        ));
  }
}

这是我使用的应用程序委托的代码：

lazy var flutterEngine = FlutterEngine()

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        flutterEngine.run()
        
        return true
    }

这是iOS viewcontroller的导航代码

let engin = (UIApplication.shared.delegate as! AppDelegate).flutterEngine
 let myflutterVC = FlutterViewController(engine: engin, nibName: nil, bundle: nil)
        myflutterVC.modalPresentationStyle = .fullScreen
        present(myflutterVC, animated: true, completion: nil)

第一个输出用于模块/运行器应用程序。
第二个输出用于我的ios应用。

iOS

为了使插件正常工作，您需要在 ios/Runner/Info.plist 中添加新密钥

<key>NSAppTransportSecurity</key>

<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSAllowsArbitraryLoadsInWebContent</key>
<true/>

颤抖的网络视图不适用于ios应用
