- TapDragUpdateDetails.new({required Offset globalPosition, required Offset localPosition, Duration? sourceTimeStamp, Offset delta = Offset.zero, double? primaryDelta, PointerDeviceKind? kind, required Offset offsetFromOrigin, required Offset localOffsetFromOrigin, required int consecutiveTapCount})
- Creates details for a GestureTapDragUpdateCallback.
Properties
- consecutiveTapCount → int
-
If this tap is in a series of taps, then this value represents
the number in the series this tap is.
final
- delta → Offset
-
The amount the pointer has moved in the coordinate space of the event
receiver since the previous update.
final
- globalPosition → Offset
-
The global position at which the pointer interacts with the screen.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- kind → PointerDeviceKind?
-
The kind of the device that initiated the event.
final
- localOffsetFromOrigin → Offset
-
A local delta offset from the point where the drag initially contacted
the screen to the point where the pointer is currently located in local
coordinates (the present localPosition) when this callback is triggered.
final
- localPosition → Offset
-
The local position in the coordinate system of the event receiver at
which the pointer interacts with the screen.
final
- offsetFromOrigin → Offset
-
A delta offset from the point where the drag initially contacted
the screen to the point where the pointer is currently located in global
coordinates (the present globalPosition) when this callback is triggered.
final
- primaryDelta → double?
-
The amount the pointer has moved along the primary axis in the coordinate
space of the event receiver since the previous
update.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- sourceTimeStamp → Duration?
-
Recorded timestamp of the source pointer event that triggered the drag
event.
