Flutter: Activate multiple gesture detectors after long press

I have an application where there is multiple cards in a grid that each have their own gesture detector. I want to be able to long press on one of the cards and then drag over the other cards and activate each cards gesture detector separately. I am not sure if this is possible.

It might be too late, but use onLongPressMoveUpdate(updates) and check localOffsetFromOrigin.dx or localOffsetFromOrigin.dy for positive and negative values for left,right,up,down drag respectively.

GestureDetector has an event onPanStart which might be what you are looking for. Listen to this event on the other Cards after the LongPress event is activated.

onPanStart

A pointer has contacted the screen and has begun to move.

or else there is another widget to look into, the swipedetector, here
