PointerMoveEvent class
The pointer has moved with respect to the device while the pointer is in contact with the device.
See also:
- PointerHoverEvent, which reports movement while the pointer is not in contact with the device.
- Listener.onPointerMove, which allows callers to be notified of these events in a widget tree.

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
-

system according to transform.
no setterinherited
- localPosition → Offset
-

finalinherited
- original → PointerEvent?
-
The original un-transformed PointerEvent before any transforms were
applied.
finalinherited
- platformData → int

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
