Properties

activeTrackSize → double
Active track size.
final
color → Color?
Bar and indicators active color.
final
divisions → int?
Number of divisions for discrete Slider.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double
MultiSlider vertical dimension. Used by GestureDetector and CustomPainter.
final
horizontalPadding → double
Empty space between the MultiSlider bar and the end of GestureDetector zone.
final
inactiveTrackSize → double
Inactive track size.
final
indicator → IndicatorBuilder?
Default indicator builder. Used to draw values, even if user is not interacting with this component. This is null by default, so you have to use defaultIndicator or define your own if you want to display values.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
max → double
MultiSlider maximum value.
final
min → double
MultiSlider minimum value.
final
onChanged → ValueChanged<List<double>>?
Callback for every user slide gesture.
final
onChangeEnd → ValueChanged<List<double>>?
Callback for every time user stop click/slide on this widget.
final
onChangeStart → ValueChanged<List<double>>?
Callback for every time user click on this widget.
final
range → double
Difference between max and min. Must be positive!
final
rangeColors → List<Color>?
Bar range colors from left to right. Your choice here will be displayed unconditionally! If you want more control, use trackbarBuilder instead!
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectedIndicator → IndicatorBuilder?
Selected indicator builder. Used to draw only the selected value. defaultIndicator is used by default. You can define your own or set null to not draw anything. If indicator is set and selectedIndicator is null, then indicator will be used to draw selected value indicator.
final
textDirection → TextDirection
TextDirection used on indicator and selectedIndicator drawing.
final
textHeightOffset → double
Height offset used in indicator and selectedIndicator.
final
thumbBuilder → ThumbBuilder
Use to set custom color, elevation and radius for each thumb indicator individually.
final
thumbColor → Color?
Thumb color.
final
thumbInactiveColor → Color?
Thumb inactive color.
final
thumbRadius → double
Thumb radius.
final
trackbarBuilder → TrackbarBuilder
Used to setup ranges draw. For a simplified use, try rangeColors. Run from left to right for each ValueRange. Return TrackbarOptions where you setup if the current track is active or not. You can override its size or Color by passing a color different from null.
final
values → List<double>
List of ordered values which will be changed by user gestures with this widget.
