我正在使用flutter Webview插件，该插件可以正常工作，但是今天在显示仅包含宽度和高度为100％的图像的网页时，我遇到了一个问题。因此，抖动的Webview显示空白页。当我将高度和宽度更改为特定的像素（例如320px和220px）时，只有webview插件显示图像，否则100％的网页将变为空白。
您可以尝试使用我的插件flutter_inappbrowser（EDIT：它已重命名为flutter_inappwebview）。
[直接将InAppWebView和img至width的height加载到100%小部件中的html源的示例：
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
Future main() async {
runApp(new MyApp());
}
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
@override
void initState() {
super.initState();
}
@override
void dispose() {
super.dispose();
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: InAppWebViewPage()
);
}
}
class InAppWebViewPage extends StatefulWidget {
@override
_InAppWebViewPageState createState() => new _InAppWebViewPageState();
}
class _InAppWebViewPageState extends State<InAppWebViewPage> {
InAppWebViewController webView;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("InAppWebView")
),
body: Container(
child: Column(children: <Widget>[
