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)?)
页面切换
final
padEnds bool
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
viewportFraction double
final
