hi !
there is an undocumented animation.js under the node_modules/ionic-angular
does anybody know how to use it or any documentation ?
Just trying to find out myself, but found this: https://angular.io/docs/ts/latest/guide/animations.html
Helped me a lot!
For everything in ionic-angular you should check the angular website for documentation.
i am using angular’s core animations class for a while now but you don’t need ionic-angular’s animation class for that. i was wondering what that class does 
The Animation class from ionic is internal only at the moment. It’s very low level and used for creating page transitions.
