有没有办法在Flutter中使用PageView进行无限循环?
问题描述：
是否可以使用Flutter中的 PageView 进行无限循环?例如，如果我的PageView有5个页面，则在滑动到第5页后，我将能够再次向同一方向滑动以进入第1页.
Is there a way to have an infinite loop using PageView in Flutter? For example if my PageView has 5 pages, after swiping to page 5, I would be able to swipe again in the same direction to get to Page 1.
答
默认情况下， PageView.builder 扑朔迷离.除非您提供 itemCount .
By default, PageView.builder is infinite in flutter. Unless you provide an itemCount.
以下内容将从0到4无限打印页面
The following will print page from 0 to 4 infinitely
final controller = new PageController(initialPage: 999);
...
new PageView.builder(
controller: controller,
itemBuilder: (context, index) {
return new Center(
child: new Text('${index % 5}'),
);
},
)
