Answer 1

Create a List. Create a listView.builder with this list. In the method add the widget to the list and it's auto populated if you set it's state.

Answer 2

ListView.builder(
        itemCount: field.length,
        itemBuilder: (BuildContext context,int index){
 String value;
    if (field is Function)
      value = field(data);
    else
      value = data.containsKey(field) ? data[field].toString() : '';
          return ListTile(
            title: Text(
      value,
      style: TextStyle(fontSize: 14),
    ),
            );
        }
        ),
