class PageView extends StatefulWidget {
/// Creates a scrollable list that works page by page from an explicit [List]
/// of widgets.
///
/// This constructor is appropriate for page views with a small number of

从显式[list]创建一个逐页工作的可滚动列表
的小部件。
此构造函数适用于数量较少的页面视图
因为构建[列表]需要为每个人做工作
可以在页面视图中显示的子元素,而不只是
这些孩子实际上是可见的。
PageView({
Key key,
this.scrollDirection = Axis.horizontal, //滚动的方向 支持水平和垂直两个方向
this.reverse = false, //是否反转滚动
PageController controller, //pageView控制类
this.physics, //手势滚动逻辑,支持:不滚动、总是滚动、与滚动到边缘时是否有bounce
this.pageSnapping = true, //设置为false以禁用页面捕捉,对自定义滚动行为很有用
this.onPageChanged, //页面切换时调用
List<Widget> children = const <Widget>[], //pageView要显示的页面
this.dragStartBehavior = DragStartBehavior.start,
}) : controller = controller ?? _defaultPageController,
childrenDelegate = SliverChildListDelegate(children),
super(key: key);
