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)

The following assertion was thrown while notifying status listeners for AnimationController:
This widget has been unmounted, so the State no longer has a context (and should be considered defunct).

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

Hi, can you provide a simple example code to reproduce this issue?

I added key to SlidableAutoCloseBehavior and error gone.

 child: SlidableAutoCloseBehavior(
                                  key: const ValueKey(
                                      "slidableAutoCloseBehavior"),
                                  child: ListView.separated(
                                    controller: scrollController,
