LeftImmediateMultiDragGestureRecognizer class
Properties
-
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
-
buttonCodes
→ List<int>
-
final
-
debugDescription
→ String
-
Returns a very short pretty description of the gesture that the
recognizer looks for, like 'tap' or 'horizontal drag'.
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
-
onStart
↔ GestureMultiDragStartCallback?
-
Called when this class recognizes the start of a drag gesture.
getter/setter pairinherited
-
runtimeType
→ Type
-
A representation of the runtime type of the object.
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.

Methods
-
acceptGesture(int pointer)
→ void
-
Called when this member wins the arena for the given pointer id.

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
-
createNewPointerState(PointerDownEvent event)
→ MultiDragPointerState
-
Subclasses should override this method to create per-pointer state
objects to track the pointer associated with the given event.
override
-
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
-
dispose()
→ void
-
Releases any resources used by the object.
inherited
-
getKindForPointer(int pointer)
→ PointerDeviceKind
-
For a given pointer ID, returns the device kind associated with it.
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
-
rejectGesture(int pointer)
→ void
-
Called when this member loses the arena for the given pointer id.
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.
