PageControllerIns(int index)

Properties

debugLabel → String?: A label that is used in the toString output. Intended to aid with identifying scroll controller instances in debug output.

no setterinherited
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
index → int: final
initialPage → int: The page to show when first creating the PageView.
finalinherited
initialScrollOffset → double: The initial value to use for offset.
no setterinherited
keepPage → bool: Save the current page with PageStorage and restore it if this controller's scrollable is recreated.
finalinherited
keepScrollOffset → bool: Each time a scroll completes, save the current scroll offset with PageStorage and restore it if this controller's scrollable is recreated.
finalinherited
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
page → double?: The current page displayed in the controlled PageView.
no setterinherited
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
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
viewportFraction → double: The fraction of the viewport that each page should occupy.

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
animateToPage(int page, {required Duration duration, required Curve curve}) → Future<void>: Animates the controlled PageView from the current page to the given page.
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.
inherited
get(Token name) → Object?: 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
jumpToPage(int page) → void: Changes which page is displayed in the controlled PageView.
inherited
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 nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
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.
