onHttpError not listening

[puntnomads]

I had run the example and onStateChanged has worked but onHttpError is not working. It is not giving an error message if there is no internet or the website is down. I am on flutter beta branch (0.4.4). I have tried many versions (0.2.0 to 0.2.1+2).

Channel beta, v0.5.1,
flutter_webview_plugin: ^0.2.1+2
On iOS it seems to work as expected.
On Android I was getting inconsistent results, a lot the time 200 status codes were being missed. I was getting a lot of 404s when I thought I should be getting 200. I played around on the server side of things and started to send 600 as a response. It always seem to catch that change.
