authData is undefined in MainCtrl

[pmurpmur]

I am just trying to run the application but I cannot get past the login screen and chrome keeps getting the following error:

TypeError: Cannot read property 'google' of undefined
at controllers.js:36
at Scope.promises.$get.Scope.$broadcast (ionic.bundle.js:23419)
at controllers.js:62
at ionic.bundle.js:44815
at Object.ionic.Platform.ready (ionic.bundle.js:2120)
at Object.IonicModule.constant.provider.$get.self.ready (ionic.bundle.js:44813)
at new (controllers.js:33)
at invoke (ionic.bundle.js:12884)
at Object.instantiate (ionic.bundle.js:12892)
at ionic.bundle.js:17161

It is basically saying that the variable 'authData' is undefined. Is there any reason for this?
