Properties

keepScrollOffset bool
Each time a scroll completes, save the current scroll offset with PageStorage and restore it if this controller's scrollable is recreated. [...]
final, inherited
debugLabel String
A label that is used in the toString output. Intended to aid with identifying scroll controller instances in debug output.
final, inherited
initialScrollOffset double
The initial value to use for offset. [...]
read-only, inherited
positions Iterable<ScrollPosition>
The currently attached positions. [...]
@protected, read-only, inherited
hasClients bool
Whether any ScrollPosition objects have attached themselves to the ScrollController using the attach method. [...]
read-only, inherited
position ScrollPosition
Returns the attached ScrollPosition, from which the actual scroll offset of the ScrollView can be obtained. [...]
read-only, inherited
offset double
The current scroll offset of the scrollable widget. [...]
read-only, inherited
hasListeners bool
Whether any listeners are currently registered. [...]
@protected, read-only, inherited
hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.

Methods

scrollToTop() → void
scrollToPreviousPage() → void
scrollUp({double offset: kPagingScrollOffset}) → void
scrollToNextPage() → void
scrollDown({double offset: kPagingScrollOffset}) → void
scrollToBottom() → void
animateTo(double offset, {Duration duration, Curve curve}) Future<void>
Animates the position from its current value to the given value. [...]
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
attach(ScrollPosition position) → void
Register the given position with this controller. [...]
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). [...]
inherited
createScrollPosition(ScrollPhysics physics, ScrollContext context, ScrollPosition oldPosition) ScrollPosition
Creates a ScrollPosition for use by a Scrollable widget. [...]
inherited
toString() String
Returns a string representation of this object.
inherited
debugFillDescription(List<String> description) → void
Add additional information to the given description for use by toString. [...]
@mustCallSuper, inherited
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes. [...]
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes. [...]
inherited
notifyListeners() → void
Call all the registered listeners. [...]
@protected, @visibleForTesting, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
