Flutter for web can not use flutter_webview_plugin

my code

`import 'package:flutter/material.dart';
import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';

// ignore: prefer_collection_literals
void main() {
// WidgetsFlutterBinding.ensureInitialized();
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// final _webViewPlugin = FlutterWebviewPlugin();
String filePath = 'files/test.html';

@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter WebView Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
routes: {
'/': (_) => new WebviewScaffold(
url: "https://www.google.com",
appBar: new AppBar(
title: const Text('Widget webview'),
),
withZoom: true,
hidden: true,

),
},
);
}
}
`

Start from the reported Flutter web target and the flutter_webview_plugin import, then check the plugin documentation and platform support. The issue includes no repository file or test entry point, so first determine whether WebviewScaffold is expected to work on Flutter web; done would require a documented or verified resolution for that platform.
