CompetitiveDragGestureRecognizer class
abstract
Methods
acceptGesture (int pointer )
→ void
Called when this member wins the arena for the given pointer id.
override
addAllowedPointer (PointerEvent event )
→ void
Registers a new pointer that's been checked to be allowed by this gesture
recognizer.
override
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.
override
didStopTrackingLastPointer (int pointer )
→ void
Called when the number of pointers this recognizer is tracking changes from one to zero.
override
dispose ()
→ void
Releases any resources used by the object.
override
getKindForPointer (int pointer )
→ PointerDeviceKind
For a given pointer ID, returns the device kind associated with it.
inherited
handleEvent (PointerEvent event )
→ void
Called when a pointer event is routed to this recognizer.
override
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
isFlingGesture (VelocityEstimate estimate , PointerDeviceKind kind )
→ bool
Determines if a gesture is a fling or not based on velocity.
isPointerAllowed (PointerEvent event )
→ bool
Checks whether or not a pointer is allowed to be tracked by this recognizer.
override
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
rejectGesture (int pointer )
→ void
Called when this member loses the arena for the given pointer id.
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
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 })
→ 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 .
