Constructors
- EasyRefresh({Key? key, EasyRefreshController? controller, OnRefreshCallback? onRefresh, OnLoadCallback? onLoad, bool enableControlFinishRefresh = false, bool enableControlFinishLoad = false, bool taskIndependence = false, ScrollController? scrollController, Header? header, bool firstRefresh = false, Widget? firstRefreshWidget, int headerIndex = 0, Widget? emptyWidget, bool topBouncing = true, bool bottomBouncing = true, bool isScrollEnabled = true, ScrollBehavior? behavior = const EmptyOverScrollScrollBehavior(), required Widget? child})
-
默认构造器
将child转换为CustomScrollView可用的slivers
const
- EasyRefresh.builder({Key? key, EasyRefreshController? controller, OnRefreshCallback? onRefresh, OnLoadCallback? onLoad, bool enableControlFinishRefresh = false, bool enableControlFinishLoad = false, bool taskIndependence = false, ScrollController? scrollController, Header? header, bool firstRefresh = false, bool topBouncing = true, bool isScrollEnabled = 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
const
-
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, 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, bool isScrollEnabled = true}) -
custom构造器(推荐)
直接使用CustomScrollView可用的slivers
