How to use ViewChild Content to access the content component and it's props.
# get ion-content component
import { Content } from 'ionic-angular';
@ViewChild(Content) content: Content;
# scroll content to top
this.content.scrollTop()
# scroll to value
this.content.scrollTo(x,y,duration);
# get ion-scroll height (this value might change depending on when requested
this.content.getElementRef().nativeElement.children[0].scrollHeight
# resize after changing content height (adding/removing height of ion-header/ion-footer
this.content.resize();
