This plugin has issues where when you navigate to a page with the ButtonCircle, the app crashes with the following error. Was working before update to v2.0.2 and latest Xamarin Forms 2.5....

@eopeter FWIW, This error usually has to do with the reference to the icon font library you are using. I was seeing this error when I was trying to load the material icon given in the example at the bottom of the main page in this repo. The icon is "md-ic-directions-bike" and should be "md-directions-bike" after I changed that it worked fine.

Yes, this is problem probably. The list of icons was changed since version 1.3.9, please check it here. I going to process close this issue.
