no setterinherited
onAttach → ScrollControllerCallback?: Called when a ScrollPosition is attached to the scroll controller.
finalinherited
onDetach → ScrollControllerCallback?: Called when a ScrollPosition is detached from the scroll controller.
finalinherited
position → ScrollPosition: Returns the attached ScrollPosition, from which the actual scroll offset of the ScrollView can be obtained.
no setterinherited

no setterinherited
scrollConfig → AntdScrollToIndexConfig: no setterinherited
scrollDelta → double: no setterinherited
targetIndex → int: no setterinherited
targetSize ↔ int: getter/setter pairinherited
viewportOffset ↔ double: 视图的offset会基于这个offset提前计算
getter/setter pairinherited
virtual ↔ bool: getter/setter pairinherited
