How to add the 'pinned item' functionality, similar to Google Keep, on a ListView?

I tried doing 2 list view, and putting the pinned one on top of a Column. But the problem is they scrolled separately, and if I wrapped the column in a Singlechildscrollview, it just gives error.

Am I on the right track of doing it or there is a way by just using a single list view?

Implement if you want:

• add an extra field to your object: bool pinned -> then you sort the list to make sure the pinned items are on top of the list
• put a GestureDetector around the item and use the onTap to set the pinned value -> pinned = !pinned

Or try this package I just found:

https://pub.dev/packages/pinnable_listview

I think I got the Singlechildscrollview worked the way I want it to. I just have to set the ListView shrinkWrap: true, and physics: NeverScrollableScrollPhysics(). I'm not sure if this is a good idea tho, since most people say that shrinkWrap is quite a heavy operation to use.

SingleChildScrollView(
            physics: ScrollPhysics(),
            child: Column(
              mainAxisAlignment: MainAxisAlignment.start,
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                Text('Pinned'),
                PinnedListItemHere(), //ListView of Pinned Items
                Divider(
                  height: 25.0,
                  thickness: 2.0,
                ),
                Text('Others'),
                UnpinnedListItemHere(), //ListView of Unpinned Items
              ],
            ),
          ),
