onSerialTapCancel property
getter/setter pair
A pointer that previously triggered onSerialTapDown will not end up triggering the corresponding onSerialTapUp.
If the user completes the serial tap, onSerialTapUp is called instead.
The SerialTapCancelDetails.count that is passed to this callback will match the SerialTapDownDetails.count that was passed to the onSerialTapDown callback.
Implementation
GestureSerialTapCancelCallback? onSerialTapCancel;
