The input from the pointer is no longer directed towards this receiver.

Properties

buttons int
Bit field using the *Button constants (primaryMouseButton, secondaryStylusButton, etc). For example, if this has the value 6 and the kind is PointerDeviceKind.invertedStylus, then this indicates an upside-down stylus with both its primary and secondary buttons pressed.
final, inherited
delta Offset
Distance in logical pixels that the pointer moved since the last PointerMoveEvent. Always 0.0 for down, up, and cancel events.
final, inherited
device int
Unique identifier for the pointing device, reused across interactions.
final, inherited
distance double
The distance of the detected object from the input surface (e.g. the distance of a stylus or finger from a touch screen), in arbitrary units on an arbitrary (not necessarily linear) scale. If the pointer is down, this is 0.0 by definition.
final, inherited
distanceMax double
The maximum value that a distance can return for this pointer. If this input device cannot detect "hover touch" input events, then this will be 0.0.
final, inherited
distanceMin double
The minimum value that a distance can return for this pointer (always 0.0).
final, inherited
down bool
Set if the pointer is currently down. For touch and stylus pointers, this means the object (finger, pen) is in contact with the input surface. For mice, it means a button is pressed.
final, inherited
hashCode int
The hash code for this object. [...]
read-only, inherited
kind PointerDeviceKind
The kind of input device for which the event was generated.
final, inherited
obscured bool
Set if an application from a different security domain is in any way obscuring this application's window. (Aspirational; not currently implemented.)
final, inherited
orientation double
For PointerDeviceKind.touch events: [...]
final, inherited
pointer int
Unique identifier for the pointer, not reused.
final, inherited
position Offset
Coordinate of the position of the pointer, in logical pixels in the global coordinate space.
final, inherited
pressure double
The pressure of the touch as a number ranging from 0.0, indicating a touch with no discernible pressure, to 1.0, indicating a touch with "normal" pressure, and possibly beyond, indicating a stronger touch. For devices that do not detect pressure (e.g. mice), returns 1.0.
final, inherited
pressureMax double
The maximum value that pressure can return for this pointer. For devices that do not detect pressure (e.g. mice), returns 1.0. This will always be a greater than or equal to 1.0.
final, inherited
pressureMin double
The minimum value that pressure can return for this pointer. For devices that do not detect pressure (e.g. mice), returns 1.0. This will always be a number less than or equal to 1.0.
final, inherited
radiusMajor double
The radius of the contact ellipse along the major axis, in logical pixels.
final, inherited
radiusMax double
The minimum value that could be reported for radiusMajor and radiusMinor for this pointer, in logical pixels.
final, inherited
radiusMin double
The minimum value that could be reported for radiusMajor and radiusMinor for this pointer, in logical pixels.
final, inherited
radiusMinor double
The radius of the contact ellipse along the minor axis, in logical pixels.
final, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
synthesized bool
We occasionally synthesize PointerEvents that aren't exact translations of ui.PointerData from the engine to cover small cross-OS discrepancies in pointer behaviors. [...]
final, inherited
tilt double
For PointerDeviceKind.stylus and PointerDeviceKind.invertedStylus events: [...]
final, inherited
timeStamp Duration
Time of event dispatch, relative to an arbitrary timeline.
final, inherited

Methods

Returns a string representation of this object.
