flutter - Flutter / webview_flutter 太大而无法适应屏幕

Question

我正在运行颤振 1.17.1，使用 webview_flutter: ^0.3.21 依赖项添加到 pubspec.yaml 并将其添加到 info.plist 的末尾

<key>io.flutter.embedded_views_preview</key>
    <string>YES</string>

问题：加载到 webview 的网页太大，手机屏幕放不下。 截屏

这是带有 webview 的代码：

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

class WebViewContainer extends StatefulWidget {
  final url;
  WebViewContainer(this.url);
  @override
  createState() => _WebViewContainerState(this.url);
}

class _WebViewContainerState extends State<WebViewContainer> {
  var _url;
  final _key = UniqueKey();
  _WebViewContainerState(this._url);
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(),
        body: Column(
          children: [
            Expanded(
                child: WebView(
                    key: _key,
                    javascriptMode: JavascriptMode.unrestricted,
                    initialUrl: _url))

          ],
        ));
  }
}

我已经尝试了使用 url "https://www.businessinsider.jp/" 和最新版本的 webview_flutter的最小复制，这是输出：

最小复制：

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(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  final Completer<WebViewController> _controller =
      Completer<WebViewController>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: WebView(
        initialUrl: "https://www.businessinsider.jp/",
        onWebViewCreated: (WebViewController webViewController) {
          _controller.complete(webViewController);
        },
        javascriptMode: JavascriptMode.unrestricted,
      ),
    );
  }
}

最新版本好像没有出现这个问题。
