PointerRemovedEvent class
The device is no longer tracking the pointer.
For example, the pointer might have drifted out of the device's hover detection range or might have been disconnected from the system entirely.

Distance in logical pixels that the pointer moved since the last
PointerMoveEvent or PointerHoverEvent.
finalinherited

finalinherited
- localDelta → Offset
-
The delta transformed into the event receiver's local coordinate
system according to transform.
no setterinherited
- localPosition → Offset
-
The position transformed into the event receiver's local coordinate
system according to transform.
no setterinherited

-
Set if an application from a different security domain is in any way
obscuring this application's window.
finalinherited

-
The original un-transformed PointerEvent before any transforms were
applied.
finalinherited
- platformData → int
-
Opaque platform-specific data associated with the event.
finalinherited

-
Coordinate of the position of the pointer, in logical pixels in the global
coordinate space.
finalinherited

finalinherited
- radiusMajor → double
-
The radius of the contact ellipse along the major axis, in logical pixels.
finalinherited
- radiusMax → double
-
The maximum value that could be reported for radiusMajor and radiusMinor
for this pointer, in logical pixels.
finalinherited
- radiusMin → double
-
The minimum value that could be reported for radiusMajor and radiusMinor
for this pointer, in logical pixels.
finalinherited
- radiusMinor → double
-

Set if the event was synthesized by Flutter.
finalinherited
- tilt → double
-
The tilt angle of the detected object, in radians.
finalinherited
- timeStamp → Duration
-
Time of event dispatch, relative to an arbitrary timeline.
finalinherited
- transform → Matrix4?
-
The transformation used to transform this event from the global coordinate
space into the coordinate space of the event receiver.
finalinherited
- viewId → int
-
The ID of the FlutterView which this event originated from.
finalinherited
