PointerDownEvent class
The pointer has made contact with the device.

Properties
-
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

-
The maximum value that distance can return for this pointer.
finalinherited
- distanceMin → double
-
The minimum value that distance can return for this pointer.
no setterinherited
- 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.
no setterinherited

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
- obscured → bool
-
Set if an application from a different security domain is in any way
obscuring this application's window.
finalinherited
- orientation → double
-
The orientation angle of the detected object, in radians.
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.

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
- 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
