how can I use flutter slidable let only one item move??not working key

Question

I use flutter_slidable: ^0.6.0. I hope working only one item slidable in my listview.
if one item slide by user, all the others(whatever open or close) r closed. some docs say use key.but mine is not working.

 return ListView.builder(
            physics: ClampingScrollPhysics(),
            itemCount: snapshot.data!.size,
            shrinkWrap: true,
            itemBuilder: (BuildContext context, count) {
             

              return Padding(
                padding: const EdgeInsets.all(8.0),
                child: Slidable(
                  key: Key(snapshot.data!.docs[count].id),
                  controller: slidableController,
                  actionPane: SlidableDrawerActionPane(),
                  actionExtentRatio: 0.25,
                  actions: <Widget>[
                    widget.pin == 0
                        ? IconSlideAction(
                            caption: 'pin 제거',
                            color: Colors.black45,
                            icon: Icons.push_pin_rounded,
                            onTap: () {
                              pinEraseRoom(widget.roomId);
                            },
                          )
                        : IconSlideAction(
                            caption: 'Pin',
                            color: Colors.black45,
                            icon: Icons.push_pin_outlined,
                            onTap: () {
                              pinRoom(widget.roomId);
                            },
                          ),
                  ],
                  secondaryActions: <Widget>[
                    IconSlideAction(
                      caption: 'Delete',
                      color: Colors.red,
                      icon: Icons.delete,
                      onTap: () {
                        deleteRoom(widget.roomId);
                      },
                    ),
                  ],
