Define Number of lists according with Number into Widget flutter - flutter

Question

What I Have are number of orders received that has be shown into a tab into a widget in flutter according with this code:
class ShipmentTab extends StatefulWidget {
#override
_ShipmentTabState createState() => _ShipmentTabState();
}
class _ShipmentTabState extends State<ShipmentTab> {
**final shipmentNumber = "16";**
#override
Widget build(BuildContext context) {
return Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Card(
color: Color(0xfffeaf0d),
child: Container(
width: 40,
height: 40,
child: Icon(
Icons.local_shipping,
color: Colors.white,
),
),
),
),
Padding(
padding: const EdgeInsets.all(13),
child: Text(
shipmentNumber,
style: TextStyle(
color: Colors.white, fontSize: 35, fontWeight: FontWeight.bold),
),
),
],
);
}
}
as you can see variable is " shipmentNumber " that show "16"
below I have listview.builder and I need to add itemCount and this count has to be refered to the tab above "16"
this is the code of the list:
Container(
height: 400,
child: ListView.builder(
shrinkWrap: true,
itemBuilder: (ctx, int) {
return Card(
color: Color(0xFF1f2032),
elevation: 15,
child: Container(
width: 60,
height: 60,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Card(
color: Color(0xfffeaf0d),
child: Container(
height: 40,
width: 40,
child: Icon(
Icons.local_shipping,
color: Colors.white,
size: 25,
)),
),
Text(
'Ref № $int',
style: TextStyle(
color: Colors.white, fontWeight: FontWeight.bold),
),
Text(
'Mario Rossi',
style: TextStyle(
fontWeight: FontWeight.bold,
color: Color(0xfffeaf0d),
),
),
Text(
'Consegnato',
style: TextStyle(color: Colors.lightGreenAccent),
),
Icon(
Icons.share,
color: Colors.white,
)
],
),
),
);
},
),
),
],
);
}
}

ListView.builder has itemCount parameter. I notice shipmentNumber is in String so you can parse it to int. Also you need to remove the Container height wrapping your ListView
ListView.builder(
shrinkWrap: true,
itemCount: int.parse(shipmentNumber),
itemBuilder: (BuildContext context, int index) {
/** build your Item here **/
return BuiltItem();
},
)
