Is there any way to trigger an action when finger is lifted off a button?

Actions & Logic

Is there any FlutterFlow equivalent of an onkeyup event listener? I want to trigger an action, but only when the user's finger lifts off a button. This would allow me to implement tap-and-hold functionality where the action runs for as long as the user's finger is held down.

What have you tried so far?

I looked everywhere and could not find such an event listener. 

Did you check FlutterFlow's Documentation for this topic?
Yes
