I am having extreme difficulty in handling this. I call an async function that will get some info from SQLite but I can't seem to get it. It just renders a empty screen in which should be a `listview`.

```dart
List allItems = new List();

Future<void> pegaDados() async {
    var itens = await geraCardapio();

    for (var i = 0; i < itens.length; i++) {
        print((itens[i].toMap()));
        allItems.add(itens[i].toMap());
    }
}

print(pegaDados());

return ListView.builder(
    itemCount: allItems.length,
    itemBuilder: (context, index) {
        return ListTile(
            leading: Image.asset("assets/"+ allItems[index]['imagem'], fit: BoxFit.contain,),
            title: Text(allItems[index]['pedido']),
            trailing: Text(allItems[index]['valor']),
        );
    },
);

```

Thank you very much.

I managed to get the solution, thanks to both people who answered the question (using both solutions I managed to get this little frankenstein)

```
Future<dynamic> pegaDados() async {
    var allItems = await geraCardapio();

    return allItems.map((allItems) => allItems.toMap());
}

return FutureBuilder(
    future: pegaDados(),
    builder: (context, snapshot) {
        if (snapshot.connectionState == ConnectionState.done) {
            print(snapshot.data);
            var objeto = [];

            for (var i in snapshot.data) {
                objeto.add(i);
            }

            print(objeto);
            return Container(
                child: ListView.builder(
                itemCount: objeto.length,
                itemBuilder: (context, index) {
                    return ListTile(
                        leading: Image.asset("assets/"+ objeto[index]['imagem'], fit: BoxFit.contain),
                        title: Text(objeto[index]['pedido']),
                        trailing: Text(objeto[index]['valor'].toString()),
                    );
                },
            ),
        );
    } else if (snapshot.hasError) {
        throw snapshot.error;
    } else {
        return Center(child: CircularProgressIndicator());
    }
});
