		@required this.itemCount,
		this.mainAxisAlignment: MainAxisAlignment.start,
		this.mainAxisSize: MainAxisSize.max,
		this.crossAxisAlignment: CrossAxisAlignment.center,
		this.textDirection,
		this.verticalDirection: VerticalDirection.down,
	}) : super(key: key);

	@override
	Widget build(BuildContext context) {
		return new Column(
