Documentation link on pub is broken

The documentation link on the right-side of the page (https://pub.dartlang.org/packages/play_phaser) is broken.

Hi @bgourlie
The doc of Dart Phaser is not finished yet. You can check the doc of JS Phaser (http://docs.phaser.io/Phaser.html)

I see. I didn't realize pub automatically added the link! Good work on the port, btw!
