Properties

affinity → Axis?
Controls how this widget competes with other gestures to initiate a drag.
finalinherited
allowedButtonsFilter → AllowedButtonsFilter?
Called when interaction starts. This limits the dragging behavior for custom clicks (such as scroll click). Its parameter comes from PointerEvent.buttons.
finalinherited
axis → Axis?
The Axis to restrict this draggable's movement, if specified.
finalinherited
child → Widget
The widget below this widget in the tree.
finalinherited
childWhenDragging → Widget?
The widget to display instead of child when one or more drags are under way.
finalinherited
data → T?
The data that will be dropped by this draggable.
finalinherited
distance → double
Distance in pixels, that must be traveled by pointer for gesture recognition.
final
dragAnchorStrategy → DragAnchorStrategy
A strategy that is used by this draggable to get the anchor offset when it is dragged.
finalinherited
feedback → Widget
The widget to show under the pointer when a drag is under way.
finalinherited
feedbackOffset → Offset
The feedbackOffset can be used to set the hit test target point for the purposes of finding a drag target. It is especially useful if the feedback is transformed compared to the child.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
hitTestBehavior → HitTestBehavior
How to behave during hit test.
finalinherited
ignoringFeedbackPointer → bool
Whether the feedback widget is ignored during hit testing.
finalinherited
ignoringFeedbackSemantics → bool
Whether the semantics of the feedback widget is ignored when building the semantics tree.
finalinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
marginZero → Widget

Available on Widget, provided by the WidgetMarginX extension

no setter
maxSimultaneousDrags → int?
How many simultaneous drags to support.
finalinherited
onDragCompleted → VoidCallback?
Called when the draggable is dropped and accepted by a DragTarget.
finalinherited
onDragEnd → DragEndCallback?
Called when the draggable is dropped.
finalinherited
onDraggableCanceled → DraggableCanceledCallback?
Called when the draggable is dropped without being accepted by a DragTarget.
finalinherited
onDragStarted → VoidCallback?
Called when the draggable starts being dragged.
finalinherited
onDragUpdate → DragUpdateCallback?
Called when the draggable is dragged.
finalinherited
paddingZero → Widget

Available on Widget, provided by the WidgetPaddingX extension

no setter
rootOverlay → bool
Whether the feedback widget will be put on the root Overlay.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sliverBox → Widget

Methods

animate({Key? key, List<Effect>? effects, AnimateCallback? onInit, AnimateCallback? onPlay, AnimateCallback? onComplete, bool? autoPlay, Duration? delay, AnimationController? controller, Adapter? adapter, double? target, double? value}) → Animate

Available on Widget, provided by the AnimateWidgetExtensions extension

Wraps the target Widget in an Animate instance, and returns the instance for chaining calls. Ex. myWidget.animate() is equivalent to Animate(child: myWidget).
createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createRecognizer(GestureMultiDragStartCallback onStart) → MultiDragGestureRecognizer
Creates a gesture recognizer that recognizes the start of the drag.
override
createState() → State<Draggable<T>>
Creates the mutable state for this widget at a given location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
marginAll(double margin) → Widget

Available on Widget, provided by the WidgetMarginX extension

A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
