Properties

acceptableDuration → Duration
Refer to the doubleTappableDuration value of the TouchRippleContext for details.
final
aliveDuration → Duration
final
allowedButtonsFilter → AllowedButtonsFilter
Called when interaction starts. This limits the dragging behavior for custom clicks (such as scroll click). Its parameter comes from PointerEvent.buttons.

context → TouchRippleContext
finalinherited
count ↔ int
The value defines number of consecutive count for the double-tap event.
getter/setter pair
currentPointerOffset → Offset
Returns the current referenceable pointer offset.
no setterinherited
debugDescription → String
Returns a very short pretty description of the gesture that the recognizer looks for, like 'tap' or 'horizontal drag'.
no setterinherited
debugLabal → String
no setteroverride
debugOwner → Object?
The recognizer's owner.
finalinherited
gestureSettings ↔ DeviceGestureSettings?
Optional device specific configuration for device gestures that will take precedence over framework defaults.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
isFocusActive ↔ bool
The value defines whether the current focus is active.
getter/setter pairinherited
onDispose ↔ GestureRecognizerDisposeCallback?
The callback function is called when this gesture recognizer disposed in the memory by flutter SDK and library.
getter/setter pairinherited
onDoubleTap → TouchRippleConsecutiveCallback
final
onDoubleTapEnd → VoidCallback?
final
onDoubleTapStart → VoidCallback?
final
onFocusEnd ↔ VoidCallback?
getter/setter pairinherited
onFocusStart ↔ VoidCallback?
getter/setter pairinherited
onlyMainButton → bool
The boolean that is whether only the main button is recognized as a gesture when the user that is using mouse device clicks on the widget.
finalinherited
originOffset → Offset
no setterinherited
pointerMoveDistance → Offset
Returns the distance the pointer has moved since it was detected.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
size → Size
Returns the current intrinsic size of the rendered widget.
no setterinherited
supportedDevices ↔ Set<PointerDeviceKind>?
The kind of devices that are allowed to be recognized as provided by supportedDevices in the constructor, or the currently deprecated kind. These cannot both be set. If both are null, events from all device kinds will be tracked and recognized.
getter/setter pairinherited
tapCount ↔ int
The value defines number of taps and updated when a pointer is up.
getter/setter pair
team ↔ GestureArenaTeam?
The team that this recognizer belongs to, if any.

Methods

accept() → void
inherited
acceptGesture(int pointer) → void
Called when this member wins the arena for the given pointer id.
override
addAllowedPointer(PointerDownEvent event) → void
Registers a new pointer that's been checked to be allowed by this gesture recognizer.
inherited
addAllowedPointerPanZoom(PointerPanZoomStartEvent event) → void
Registers a new pointer pan/zoom that's been checked to be allowed by this gesture recognizer.
inherited
addPointer(PointerDownEvent event) → void
Registers a new pointer that might be relevant to this gesture detector.
inherited
addPointerPanZoom(PointerPanZoomStartEvent event) → void
Registers a new pointer pan/zoom that might be relevant to this gesture detector.
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
didStopTrackingLastPointer(int pointer) → void
Called when the number of pointers this recognizer is tracking changes from one to zero.
inherited
dispose() → void
Releases any resources used by the object.
override
ensureFocusEnd() → void
Ensures that focus is deactivated if it is currently active. This method guarantees that focus will be properly ended in situations where it remains active.
inherited
focusEnd() → void
Invokes the onFocusEnd callback when a focus gesture is finished. Therefore, this method should be called whena consecutive events ended.
override
focusStart() → void
Invokes the onFocusStart callback when a focus gesture is initiated. Therefore, this method should be called when consecutive events started.
override
getKindForPointer(int pointer) → PointerDeviceKind
For a given pointer ID, returns the device kind associated with it.
inherited
handleEvent(PointerEvent event) → void
Defines the values needed to process the gesture and calls the callback function corresponding to the given event.
inherited
handleNonAllowedPointer(PointerDownEvent event) → void
Handles a pointer being added that's not allowed by this recognizer.
inherited
handleNonAllowedPointerPanZoom(PointerPanZoomStartEvent event) → void
Handles a pointer pan/zoom being added that's not allowed by this recognizer.
inherited
hold() → void
Defines to keep the tracking state even if the pointer currently being tracked is not detected.
inherited
invokeCallback<T>(String name, RecognizerCallback<T> callback, {String debugReport()?}) → T?
Invoke a callback provided by the application, catching and logging any exceptions.
inherited
isPointerAllowed(PointerDownEvent event) → bool
Checks whether or not a pointer is allowed to be tracked by this recognizer.
inherited
isPointerPanZoomAllowed(PointerPanZoomStartEvent event) → bool
Checks whether or not a pointer pan/zoom is allowed to be tracked by this recognizer.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onPointerCancel(PointerCancelEvent event) → void
inherited
onPointerDown(PointerDownEvent event) → void
override
onPointerMove(PointerMoveEvent event) → void
inherited
onPointerUp(PointerUpEvent event) → void
override
reject() → void
inherited
rejectByOffset(Offset offset) → bool
Returns whether to reject the gesture based on the given pointer offset.
inherited
rejectGesture(int pointer) → void
Called when this member loses the arena for the given pointer id.
inherited
releaseAll() → void
Release all currently tracking pointers.
inherited
resolve(GestureDisposition disposition) → void
Resolves this recognizer's participation in each gesture arena with the given disposition.
inherited
resolvePointer(int pointer, GestureDisposition disposition) → void
Resolves this recognizer's participation in the given gesture arena with the given disposition.
inherited
startTrackingPointer(int pointer, [Matrix4? transform]) → void
Causes events related to the given pointer ID to be routed to this recognizer.
inherited
stopTrackingIfPointerNoLongerDown(PointerEvent event) → void
Stops tracking the pointer associated with the given event if the event is a PointerUpEvent or a PointerCancelEvent event.
inherited
stopTrackingPointer(int pointer) → void
Stops events related to the given pointer ID from being routed to this recognizer.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
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
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
