ionicScroller is an Angular.js and Ionic Framework extension for simple scroll-top, -bottom, -to functionality.

• run bower install ionic-scroller
• or run npm install ionic-scroller
• or download zip from release page: https://github.com/KillerCodeMonkey/ionicScroller/releases

• load ionic, ionic-scroller scripts in your index.html
• add dependency to your app module var myAppModule = angular.module('ionicScrollerTest', ['ionic', 'ionicScroller']);
• use directives in your html --> ion-scroller-top, ion-scroller-bottom, ion-scroller-to, ion-scroller-anchor
• <ion-scroller-top css-class="button button-assertive" offset="20" text="UP!" scroll-delegate="delegateHandle" animate="true"></ion-scroller-top>
• the generated buttons are hidden on shown with ng-show/ng-hide, so you can animate showing and hiding of the buttons through css as well ;)
• add class with absolute position to move button over your list ;)

• change button text: text="YOUR TEXT OR EMPTY" (default: Top / Bottom)
• animate scrolling: animate="true" (default false)
