FSliderController class abstract

A controller that manages a slider's active track.

This class should be extended to customize selection. By default, the following controllers are provided:

Inheritance

Implementers

Constructors

FSliderController({required FSliderSelection selection, FSliderInteraction allowedInteraction = FSliderInteraction.tapAndSlideThumb, bool tooltips = true, bool minExtendable = false}): Creates a FSliderController for selecting a single value.
FSliderController.range({required FSliderSelection selection, bool tooltips = true}): Creates a FSliderController for selecting a range.

allowedInteraction → FSliderInteraction: The allowed ways to interaction with the slider. Defaults to FSliderInteraction.tapAndSlideThumb.
final
disposed → bool: True if this notifier has been disposed.
no setterinherited
extendable → ({bool max, bool min}): Whether the active track is extendable at its min and max edges.
final
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
selection ↔ FSliderSelection: The slider's active track/selection.
getter/setter pair
tooltips → FSliderTooltipsController: True if the registered tooltip(s) should be shown when the user interacts with the slider. Defaults to true.
final

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
attach(double extent, List<FSliderMark> marks) → void: Registers the controller to a slider with the given extent and marks.
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
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
reset() → void: Resets the controller to its initial state.
slide(double offset, {required bool min}) → void: Slides the active track to the given offset on the min edge, in logical pixels.
step({required bool min, required bool extend}) → void: Moves the active track on the min edge to the previous/next step.
tap(double offset) → bool?: Taps the slider at given offset, in logical pixels, along the track.
toString() → String: A string representation of this object.
