FContinuousSliderController class

A controller that manages a slider's active track which represents a continuous range/value.

Inheritance

Constructors

FContinuousSliderController({required FSliderSelection selection, double stepPercentage = 0.05, bool tooltips = true, FSliderInteraction allowedInteraction = FSliderInteraction.tapAndSlideThumb, bool minExtendable = false})
Creates a FContinuousSliderController for selecting a single value.
FContinuousSliderController.range({required FSliderSelection selection, double stepPercentage = 0.05, bool tooltips = true})
Creates a FContinuousSliderController for selecting a range.

Properties

allowedInteraction FSliderInteraction
The allowed ways to interaction with the slider. Defaults to FSliderInteraction.tapAndSlideThumb.
finalinherited
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.
finalinherited
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 pairinherited
stepPercentage double
The percentage of the track that represents a single step. Defaults to 0.05.
final
tooltips FSliderTooltipsController

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
attach(double extent, List<FSliderMark> _) → void
Registers the controller to a slider with the given extent and marks.
override
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.
override
slide(double offset, {required bool min}) → void
Slides the active track to the given offset on the min edge, in logical pixels.
inherited
step({required bool min, required bool extend}) → void
Moves the active track on the min edge to the previous/next step.
inherited
tap(double offset) bool?
Taps the slider at given offset, in logical pixels, along the track.
inherited
toString() String
A string representation of this object.
