I am having custom back buttons which does not use the history !
I am unable to get the slide animation to go back in custom back events !
Any idea how to do it ?
The “back.animation” is handled over the $ionicView history.
If you manipulate the this you will get the back-transition-animation.
search for the $ionicViewService in the github sourcecode.
It is an undocumented part. Please be careful with that
