Hi,
I want to remove item without open dropdown and unchecked item from multiple dialog, i have set custom chip and want to remove item from top, here i am showing an example screen with you.

`
selectedValueWidgetFn: (item) {
return (Center(
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10),
side: BorderSide(
color: Colors.brown,
width: 0.5,
),
),
margin: EdgeInsets.all(12),
child: Padding(
padding: const EdgeInsets.all(8),
child: Chip(
label: Text(
item.toString(),
),
avatar: InkWell(
onTap: () {

                    },
                    child: Icon(
                      Icons.close,
                    ),
                  ),
                ),
              ))));
    },
