Unknown provider: LoadingProvider <- Loading

I am having trouble getting the Loading Indicator to well load. Here is what my controller lookins like:

  .controller('LoginController', function($scope, AuthService, $http, $location, Loading) { 

});

I just get the error: Unknown provider: LoadingProvider <- Loading

Did I miss a step?

Since 0.9.20, Loading is $ionicLoading

Oh would be nice if the docs indicated that. Thanks!

so can you please tell me what do you have to do to make it work??? and what’s that 0.9.20 ?? is it a version of ionic alpha how can I update my version
