I think the DocumentCompleted event will get fired for all child documents that are loaded as well (like JS and CSS, for example). You could look at the WebBrowserDocumentCompletedEventArgs in DocumentCompleted and check the Url property and compare that to the Url of the main page.

TL;DR This is now implemented as Plugin const url = “https://flutter.io”; if (await canLaunchUrl(url)) await launchUrl(url); else // can’t launch url, there is some error throw “Could not launch $url”; Full example: import ‘package:flutter/material.dart’; import ‘package:url_launcher/url_launcher.dart’; void main() { runApp(new Scaffold( body: new Center( child: new RaisedButton( onPressed: _launchURL, child: new Text(‘Show Flutter homepage’), ), … Read more
