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
animateToDate(DateTime date, {required Duration duration, required Curve curve}) Future<void>
animateToPage(int page, {required Duration duration, required Curve curve}) Future<void>
Animates the controlled PageView from the current page to the given page. [...]
override
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. [...]
@mustCallSuper, 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 and removeListener will throw after the object is disposed). [...]
override
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
jumpToDate(DateTime date) → void
jumpToPage(int page) → void
Changes which page is displayed in the controlled PageView. [...]
override
nextPage({required Duration duration, required Curve curve}) Future<void>
Animates the controlled PageView to the next page. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
notifyListeners() → void
Call all the registered listeners. [...]
previousPage({required Duration duration, required Curve curve}) Future<void>
Animates the controlled PageView to the previous page. [...]
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes. [...]
inherited
toString() String
A string representation of this object. [...]
