Actually, it's probably better to avoid NumberAnimation. In your case it's not the best thing to use since your "to" value keeps changing.

A better option is SmoothedAnimation, which smoothly moves towards the "to" value even if it changes, and you can set a velocity instead of a fixed duration. However there's a current bug that causes a jump at the end if the delegate heights have changed.

But, if you are just scrolling to the end, then the easiest option of all is to just set the current item index:

	ListView {
		id: lv
		anchors.fill: parent
		model: visualModel
		spacing: 10

		states: State {
			name: "scrolling"
			when: lv.contentHeight > 0 && !lv.moving 
			PropertyChanges { target: lv; currentIndex: visualModel.count - 1 }
		}
      }
