Constructors
- InfinitePageView({required int count, required Widget buildItem(BuildContext context, int index), double viewportFraction = 1.0, bool padEnds = true, void onPageChange(int pageIdnex)?, void onControllerListener(PageController controller)?, bool autoScroll = false, bool cycleRolling = true, int autoPlaySeconds = delayPlaySeconds, Duration animateDuration = kTabScrollDuration, int initIndex = 0, int countMultiple = 1})
Properties
- animateDuration → Duration
-
轮播动画时间
final
- autoPlaySeconds → int
-
轮播间隔时间 , 默认4s
final
- autoScroll → bool
-
支持自动轮播 默认false
final
- buildItem → Widget Function(BuildContext context, int index)
-
构建item
final
- count → int
-
page数量
final
- countMultiple → int
-
系数
例如
1,2,3
,countMultiple = 5,那实际的个数就是15,业务方还是正常使用 参考了其他方案,index个数都是无限大,这个对于内存肯定是个大问题,除非用key复用,但这样对于业务方来说就显的比较复杂了final - cycleRolling → bool
-
无限滚动
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- initIndex → int
-
初始化位置
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onControllerListener → void Function(PageController controller)?
-
控制器监听器
final
- onPageChange → void Function(int pageIdnex)?
-

final
- padEnds → bool
-
final
- runtimeType → Type
-
