Improve with loading indicator

[leynier]

I think it's a good idea to have a spinner or something similar that indicates that the page is loading, because it is uncomfortable to touch a link and feel that it does nothing.

Completely agree with you, I'm thinking in a top loading bar like Google Chrome.
Also, I'm analyzing switching webview_flutter to flutter_webview_plugin due to certain errors in the package that I issued in the flutter repository.
flutter/flutter#48696
