Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
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.
override
debugFillDescription(List<String> description) → void
Add additional information to the given description for use by toString.
@mustCallSuperinherited
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
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 non-existent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
startFooterRefresh() → void
startHeaderRefresh() → void
toString() String
A string representation of this object.
