EasyRefresh class Null safety

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
