Flutter / webview_flutter too big to fit screen - flutter

Question

I am running flutter 1.17.1, using webview_flutter: ^0.3.21
dependencies added to pubspec.yaml and added this to the end of info.plist
<key>io.flutter.embedded_views_preview</key>
<string>YES</string>
Problem: Webpage loaded into webview is too big to fit mobile phone screen.

Here is the code with the webview:
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))
],
));
}
}

Answer 1

I've tried a minimal repro with the url "https://www.businessinsider.jp/" and the latest version of webview_flutter, this is the output:
Minimal repro:
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,
),
);
}
}
It seems that the issue doesn't occur in the latest version.

Use InAppWebView instead of WebView.
This will add a line like this to your package's pubspec.yaml:
dependencies:
flutter_inappwebview: ^5.3.2
Here is a code example:
return InAppWebView(
initialOptions: InAppWebViewGroupOptions(
android: AndroidInAppWebViewOptions(
useHybridComposition: true,
textZoom: 100 * 2 // it makes 2 times bigger
)
),
onWebViewCreated: (InAppWebViewController controller) {
webViewController = controller;
controller.loadData(data: widget.html, mimeType: "text/html");
},
);
If you want to make it smaller, you just need to divide it as below:
textZoom: 100 / 2 // it makes 2 times smaller
