Properties

axis → Axis
The axis on which the slider should be displayed. Can be either vertical or horizontal.
final
centeredOrigin → bool
Determines whether the slider should be centered at the origin of the slider axis.
final
containerHeightFactor → double
This factor is timesed by the height of the height of the slider. It must be greater than 0.
final
decoration → BoxDecoration?
The decoration to apply to the slider.
final
disabled → bool
Determines whether the slider should be disabled.
final
fixedValues → List<FlutterSliderFixedValue>?
A list of fixed values that can be selected on the slider.
final
foregroundDecoration → BoxDecoration?
The foreground decoration to apply to the slider.
final
handler → FlutterSliderHandler?
The custom handler widget to use for the left handler.
final
handlerAnimation → FlutterSliderHandlerAnimation
The animation settings for the slider handlers.
final
handlerHeight → double?
The height of the slider handler.
final
handlerWidth → double?
The width of the slider handler.
final
hashCode → int
The hash code for this object.
no setterinherited
hatchMark → FlutterSliderHatchMark?
The settings for the slider hatch mark.
final
ignoreSteps → List<FlutterSliderIgnoreSteps>
A list of values that should be ignored when snapping to fixed values.
final
jump → bool
Determines whether the slider should snap to fixed values.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
lockDistance → double?
The maximum distance between the two handles to lock the handles together.
final
lockHandlers → bool
Determines whether the handles should be locked together when dragging.
final
max → double?
The maximum value that can be selected on the slider.
final
maximumDistance → double
The maximum distance between the two handles of a range slider.
final
min → double?
The minimum value that can be selected on the slider.
final
minimumDistance → double
The minimum distance between the two handles of a range slider.
final
onDragCompleted → (dynamic Function(int handlerIndex, dynamic lowerValue, dynamic upperValue)?)
Callback function that is called when the user stops dragging one of the handlers.
final
onDragging → (dynamic Function(int handlerIndex, dynamic lowerValue, dynamic upperValue)?)
Callback function that is called while the user is dragging one of the handlers.
final
onDragStarted → (dynamic Function(int handlerIndex, dynamic lowerValue, dynamic upperValue)?)
Callback function that is called when the user starts dragging one of the handlers.
final
rangeSlider → bool
Determines whether this is a range slider or a single-value slider.
final
rightHandler → FlutterSliderHandler?
The custom handler widget to use for the right handler, if this is a range slider.
final
rtl → bool
Determines whether the slider should be displayed right-to-left.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectByTap → bool
Determines whether a tap on the slider should set the nearest handle to that position.
final
step → FlutterSliderStep
The settings for the slider step.
final
tooltip → FlutterSliderTooltip?
