Showing database in flutter

I have a problem with showing a database in my app. Here's the code.

SingleChildScrollView(
  child: Center(
    child: Padding(
      padding: const EdgeInsets.all(8.0),
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: <Widget>[
          StreamBuilder(
              stream: myRef.orderByKey().limitToFirst(10).onValue,
              builder: ((context, snapshot) {
                if (snapshot.hasData) {
                  final itemInfo = Map<String, dynamic>.from(
                      (snapshot.data!).snapshot.value as Map);
                  itemInfo.forEach((key, value) {
                    final nextItem = Map<String, dynamic>.from(value);
                    for (int i = 0; i < itemInfo.length; i++) {
                      List<dynamic> item = List.empty(growable: true);
                      item.add(key.toString());
                      item.add(nextItem['Descripcion']);
                      item.add(nextItem['Cant']);
                      item.add(nextItem['Ubicacion']);
                      item.add(nextItem['Um']);
                      item.add(nextItem['X']);
                      itemsList.add(item);
                    }
                  });
                }
                return Text('${itemsList.toString()}\n');
              })),
        ],
      ),
    ),
  ),
),

Here's the app screen

The problem is that the StreamBuilder is showing the first 10 values from the database 10 times. I want to show only one time.

SOLVED

The StreamBuilder works like a loop, too. So the for loop was needless here.

So, the code changes to this:

if (snapshot.hasData) {
                  final itemInfo = Map<String, dynamic>.from(
                      (snapshot.data!).snapshot.value as Map);
                  itemInfo.forEach((key, value) {
                    final nextItem = Map<String, dynamic>.from(value);
                    List<dynamic> item = List.empty(growable: true);
                    item.add(key.toString());
                    item.add(nextItem['Descripcion']);
                    item.add(nextItem['Cant']);
                    item.add(nextItem['Ubicacion']);
                    item.add(nextItem['Um']);
                    item.add(nextItem['X']);
                    itemsList.add(item);
                  });
                }
