To do this, all the elements in the Stack have GestureDetector, and onPanUpdate made the elements move together in the direction the cursor moves. In the process of onPanDown->onPanEnd->onPanDown->onPanUpdate, the elements are placed on top as desired and move well. But if I go straight through the process of onPanDown->onPanUpdate, other elements will move.
If I do not change the order of the lists in the stack (when I go from onPanDown to onPanUpdate), it works fine. but if I do so, onPanUpdate does not apply to the widget you want. How do we solve this?

I changed GestureDetector behaviors and I changed the order of logic in various ways. But it doesn't work.
