数据
getter/setter pairinherited

no setterinherited
offset → double
The current scroll offset of the scrollable widget.
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
positions → Iterable<ScrollPosition>
The currently attached positions.
no setterinherited
previousOffset → double

reBuild ↔ void Function()
重新build
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scrollDelta → double
no setterinherited
targetIndex → int
no setterinherited
viewportOffset ↔ double
视图的offset会基于这个offset提前计算

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
addMetricsListener(AntdOnScrollMetrics? listener) → void
inherited
addPositionListener(AntdItemPositionListener<AntdCollapseItem>? callback) → void
inherited
animateTo(double offset, {required Duration duration, required Curve curve}) → Future<void>
Animates the position from its current value to the given value.
inherited
attach(ScrollPosition position) → void
Register the given position with this controller.
inherited
createScrollPosition(ScrollPhysics physics, ScrollContext context, ScrollPosition? oldPosition) → ScrollPosition
Creates a ScrollPosition for use by a Scrollable widget.
inherited
debugFillDescription(List<String> description) → void
Add additional information to the given description for use by toString.
inherited
detach(ScrollPosition position) → void
Unregister the given position with this controller.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
getCurrentItemLength() → double?
inherited
getCurrentItemTopOffset(AntdEdge viewportAlign) → double?
inherited
getItemLength(int index) → double?
inherited
getItemOffset(int index, AntdEdge viewportAlign, AntdEdge itemAlign) → double?
inherited
getItemTopOffset(int index, AntdEdge viewportAlign) → double?
inherited
getViewOffset(AntdEdge viewportAlignLine) → double
inherited
getWindowOffset({required int index, required AntdEdge viewportAlign, double offset = 0}) → double?
inherited
jumpTo(double value) → void
Jumps the scroll position from its current value to the given value, without animation, and without checking if the new value is in range.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
onMetricsUpdate() → void
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeMetricsListener(AntdOnScrollMetrics? listener) → void
inherited
removePositionListener(AntdItemPositionListener<AntdCollapseItem> callback) → void
inherited
reset() → void
inherited
toIndex(int index, {AntdScrollToIndexConfig config = const AntdScrollToIndexConfig()}) → Future<void>
inherited
toString() → String
A string representation of this object.
inherited
updateActiveIndex([AntdEdge? viewportAlignLine]) → void
inherited
updateChildSize(Size size) → bool
inherited

Operators
