PointerSignalEvent class Null safety

An event that corresponds to a discrete pointer signal.

Pointer signals are events that originate from the pointer but don't change the state of the pointer itself, and are discrete rather than needing to be interpreted in the context of a series of events.

Constructors

PointerSignalEvent({Duration timeStamp = Duration.zero, int pointer = 0, PointerDeviceKind kind = PointerDeviceKind.mouse, int device = 0, Offset position = Offset.zero, int embedderId = 0})
Abstract const constructor. This constructor enables subclasses to provide const constructors so that they can be used in const expressions.

Properties

buttons → int
Bit field using the *Button constants such as kPrimaryMouseButton, kSecondaryStylusButton, etc.
finalinherited
delta → Offset
Distance in logical pixels that the pointer moved since the last PointerMoveEvent or PointerHoverEvent.
finalinherited
device → int
Unique identifier for the pointing device, reused across interactions.
finalinherited
distance → double
The distance of the detected object from the input surface.
finalinherited

finalinherited
distanceMin → double
The minimum value that distance can return for this pointer.
read-onlyinherited
down → bool
Set if the pointer is currently down.
finalinherited
embedderId → int
Unique identifier that ties the PointerEvent to the embedder event that created it.
finalinherited
hashCode → int
The hash code for this object.
read-onlyinherited
kind → PointerDeviceKind

finalinherited
original → PointerEvent?
The original un-transformed PointerEvent before any transforms were applied.
finalinherited
platformData → int
Opaque platform-specific data associated with the event.
finalinherited
pointer → int
Unique identifier for the pointer, not reused. Changes for each new pointer down event.

finalinherited
timeStamp → Duration
Time of event dispatch, relative to an arbitrary timeline.

Creates a copy of event with the specified properties replaced.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
mustCallSuper">@mustCallSuperprotected">@protectedinherited

Invoked when a non-existent method or property is accessed.
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
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
inherited
transformed(Matrix4? transform) → PointerEvent
Transforms the event from the global coordinate space into the coordinate space of an event receiver.
