  map.forEach((key, value) {
        // here you can write your logic using "Value object",
       // make new object of your list view item and
       // add it to it's  builder list using 

       setState(() {
          _builderList.insert(0, itemObject);
       });

   });

or you can try

 final list = map.values.toList(growable: {true/false});
// play with your list
