EasyRefresh class

EasyRefresh 下拉刷新,上拉加载组件

Inheritance

Constructors

EasyRefresh({Key? key, EasyRefreshController? controller, OnRefreshCallback? onRefresh, OnLoadCallback? onLoad, bool enableControlFinishRefresh = false, bool enableControlFinishLoad = false, bool taskIndependence = false, ScrollController? scrollController, Header? header, Footer? footer, bool firstRefresh = false, Widget? firstRefreshWidget, int headerIndex = 0, Widget? emptyWidget, bool topBouncing = true, bool bottomBouncing = true, ScrollBehavior? behavior = const EmptyOverScrollScrollBehavior(), required Widget? child})
默认构造器 将child转换为CustomScrollView可用的slivers
EasyRefresh.builder({Key? key, EasyRefreshController? controller, OnRefreshCallback? onRefresh, OnLoadCallback? onLoad, bool enableControlFinishRefresh = false, bool enableControlFinishLoad = false, bool taskIndependence = false, ScrollController? scrollController, Header? header, Footer? footer, bool firstRefresh = false, bool topBouncing = true, bool bottomBouncing = true, ScrollBehavior? behavior = const EmptyOverScrollScrollBehavior(), required EasyRefreshChildBuilder? builder})
自定义构造器 用法灵活,但需将physics、header和footer放入列表中
EasyRefresh.custom({Key? key, Key? listKey, EasyRefreshController? controller, OnRefreshCallback? onRefresh, OnLoadCallback? onLoad, bool enableControlFinishRefresh = false, bool enableControlFinishLoad = false, bool taskIndependence = false, Header? header, int headerIndex = 0, Footer? footer, Axis scrollDirection = Axis.vertical, bool reverse = false, ScrollController? scrollController, bool? primary, bool shrinkWrap = false, Key? center, double anchor = 0.0, double? cacheExtent, int? semanticChildCount, DragStartBehavior dragStartBehavior = DragStartBehavior.start, bool firstRefresh = false, Widget? firstRefreshWidget, Widget? emptyWidget, bool topBouncing = true, bool bottomBouncing = true, ScrollBehavior? behavior = const EmptyOverScrollScrollBehavior(), required List<Widget>? slivers})
custom构造器(推荐) 直接使用CustomScrollView可用的slivers

final
child → Widget?
子组件
final

空视图 当不为null时,只会显示空视图 保留headerIndex以上的内容
final
enableControlFinishLoad → bool
是否开启控制结束加载
final
enableControlFinishRefresh → bool
是否开启控制结束刷新
final
firstRefresh → bool
首次刷新
final
firstRefreshWidget → Widget?
首次刷新组件 不设置时使用header
final
Footer
final
hashCode → int
The hash code for this object.
no setterinherited
Header
final
headerIndex → int
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
listKey → Key?
CustomListView Key
final
onLoad → OnLoadCallback?
加载回调(null为不开启加载)
final
onRefresh → OnLoadCallback?
刷新回调(null为不开启刷新)
final

final
reverse → bool
反向
final
runtimeType → Type

final
scrollDirection → Axis
列表方向
final
semanticChildCount → int?
final
shrinkWrap → bool
final
slivers → List<Widget>?
Slivers集合
final
taskIndependence → bool
任务独立(刷新和加载状态独立)
final
topBouncing → bool
顶部回弹(Header的overScroll属性优先，且onRefresh和header都为null时生效)
final
