This plugin isn't working in flutter web. After launching the webview the spinner keeps on spinning with no errors.

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

String url = "https://google.com/";

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@OverRide
Widget build(BuildContext context) {
return MaterialApp(
title: 'Webview Example',
theme: ThemeData.dark(),
routes: {
"/": () => Home(),
"/webview": () => WebviewScaffold(
url: url,
appBar: AppBar(
title: Text("WebView"),
),
withJavascript: true,
withLocalStorage: true,
withZoom: true,
)
},
);
}
}

class Home extends StatefulWidget {
@OverRide
HomeState createState() => HomeState();
}

class HomeState extends State {
final webView = FlutterWebviewPlugin();
TextEditingController controller = TextEditingController(text: url);

@OverRide
void initState() {
super.initState();

webView.close();
controller.addListener(() {
  url = controller.text;
});

}

@OverRide
void dispose() {
webView.dispose();
controller.dispose();
super.dispose();
}

@OverRide
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("WebView"),
),
body: Center(
child: Column(
children: [
Container(
padding: EdgeInsets.all(10.0),
child: TextField(
controller: controller,
),
),
RaisedButton(
child: Text("Open Webview"),
onPressed: () {
Navigator.of(context).pushNamed("/webview");
},
)
],
),
));
}
}

Same problem :(

Same issue here.

These are the exceptions I get in the developer console:

Overflow on channel: flutter_webview_plugin. Messages on this channel are being discarded in FIFO fashion. The engine may not be running or you need to adjust the buffer size if of the channel.

I switched to use an alternative approach and now just launch a new tab using url_launcher on web.

My use case is to provide additional features on top of the web view, so this alternative approach doesn't work for me @dazza5000. If anybody figures out any other way, I'll be obliged :)

I build my own small plugin what implements this and on start it checks kIsWeb constant (comes from Flutter) and if its false, I use this plugin. However if it's true, I'm on Flutter Web and I can build some other way to manage what I'm trying to do.

From what I gather, web isn't implemented. Web required registerWith function for a plugin.

I think this really is a missing feature...however, this creates a webview for Android and iOS. What would that actually be on a browser? Iframe? Container with HTML content inside it?

Would be handy to have something like this implemented. Works very well for OAUTH2 login for example.

I think iframeelement might be an acceptable web approach

Hi guys!

I'm really interested to help on this. @villematti do you have any update about your work?

[villematti]

@ach4m0 Nothing progressive really. I ended up using that kIsWeb variable and that does work well enough in my current project.

I'm planing on getting back to this when I have more time.

For now you can use this plugin. However, there are some issues with iframes being rerendered (see #53253 ) but there is a partial fix that is under review.
