when I wrap the Slidable component with the SlidableAutoCloseBehavior component, closing the ActionPane throws an error

flutter：3.7
flutter_slidable：3.1.0
ios simulator：15 pro max(ios 17.5)

════════ Exception caught by animation library ═════════════════════════════════
The following assertion was thrown while notifying status listeners for AnimationController:

Consider canceling any active work during "dispose" or using the "mounted" getter to determine if the State is still active.

I added key to SlidableAutoCloseBehavior and error gone.

 child: SlidableAutoCloseBehavior(

                                      "slidableAutoCloseBehavior"),
                                  child: ListView.separated(
                                    controller: scrollController,
