在Flutter for iPhone中从UIWebView转换到WKwebview

Question

webview_flutter: 0.3.20+2

大家好,我对flutter非常陌生，所以我为Android网站创建了webview, Google play接受了它。现在我读到苹果不再接受这样的应用程序了。解决方案是什么?

我没有找到任何关于这个主题的文章。有谁能帮忙吗?提前谢谢你。

下面是代码:

import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'dart:async';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'x',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(
title: 'x',
url: 'https://apple.de/'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title, this.url});
final String title;
final String url;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
WebViewController _controller;
final Completer<WebViewController> _controllerCompleter =
Completer<WebViewController>();
//Make sure this function return Future<bool> otherwise you will get an error
Future<bool> _onWillPop(BuildContext context) async {
if (await _controller.canGoBack()) {
_controller.goBack();
return Future.value(false);
} else {
return Future.value(true);
}
}
@override
Widget build(BuildContext context) {
return WillPopScope(
onWillPop: () => _onWillPop(context),
child: Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: SafeArea(
child: WebView(
key: UniqueKey(),
onWebViewCreated: (WebViewController webViewController) {
_controllerCompleter.future.then((value) => _controller = value);
_controllerCompleter.complete(webViewController);
},
javascriptMode: JavascriptMode.unrestricted,
initialUrl: widget.url,
)),
),
);
}
}

使用最新版本升级您的webview_flutter包，因为该包现在已支持WkWebView for iOS。
