delta property

Offset delta
final

The amount the pointer has moved in the coordinate space of the event receiver since the previous update.

If the GestureTapDragUpdateCallback is for a one-dimensional drag (e.g., a horizontal or vertical drag), then this offset contains only the delta in that direction (i.e., the coordinate in the other direction is zero).

Defaults to zero if not specified in the constructor.

Implementation

final Offset delta;
