TouchRippleTapGestureRecognizer({required BuildContext context, required TouchRippleRejectBehavior rejectBehavior})

Properties

acceptableDuration ↔ Duration?

getter/setter pair

context → BuildContext

final, inherited

currentPointerOffset → Offset

Returns the current referenceable pointer offset.

no setter, inherited

debugDescription → String

Returns a very short pretty description of the gesture that the recognizer looks for, like 'tap' or 'horizontal drag'.

no setter, inherited

debugLabal → String

no setter, override

debugOwner → Object?

The recognizer's owner.

final, inherited

gestureSettings ↔ DeviceGestureSettings?

Optional device specific configuration for device gestures that will take precedence over framework defaults.

getter/setter pair, inherited

hashCode → int

The hash code for this object.

no setter, inherited

isAddedPointer ↔ bool

getter/setter pair, inherited

isInterlinkable → bool

no setter, override

onAcceptedCallBack ↔ TouchRippleAcceptedCallback?

getter/setter pair, inherited

onAcceptedCalled ↔ bool

getter/setter pair, inherited

onRejectableCallBack ↔ TouchRippleRejectableCallback?

getter/setter pair, inherited

onRejectableCalled ↔ bool

getter/setter pair, inherited

onRejectedCallBack ↔ TouchRippleRejectedCallback?

getter/setter pair, inherited

onRejectedCalled ↔ bool

getter/setter pair, inherited

onTap ↔ TouchRippleRecognizerCallback?

getter/setter pair

pointerMoveDistance → Offset

Returns the distance the pointer has moved since it was detected.

no setter, inherited

previewMinDuration ↔ Duration?

getter/setter pair

rejectableState ↔ TouchRippleState?

getter/setter pair, inherited

rejectBehavior → TouchRippleRejectBehavior

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

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 pair, inherited

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.

inherited

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

inherited

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

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

onAccept() → void

override

onAccepted() → void

inherited

onPointerCancel(PointerCancelEvent event) → void

inherited

inherited

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

reset() → void

A callback function that is called to define all the member variables of this class to their initial values if the gesture is rejected or accepted.

override

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
