o trecho do codigo q esta dando erro e

StreamBuilder( stream: FirebaseFirestore.instance.collection('nomes').snapshots(), builder: (BuildContext context, AsyncSnapshot snapshot) { if (snapshot.hasError) { return Text('Erro ao carregar os nomes'); }

                                  if (snapshot.connectionState == ConnectionState.waiting) {
                                    return CircularProgressIndicator();
                                  }

                                  // Exibir os nomes salvos
                                  final List<QueryDocumentSnapshot> documents = snapshot.data!.docs;
                                  return Column(
                                    crossAxisAlignment: CrossAxisAlignment.start,
                                    children: documents
                                        .map((QueryDocumentSnapshot document)  => ElevatedButton(
                                          onPressed: (){
                                            int voto = document['voto'];
                                            getVoto(
                                              voto+1,
                                              document['nome']
                                            );
                                            Navigator.of(context).pushNamed('/votos');
                                          },
                                          child: Text(document['nome']))
                                        ).toList(),
                                  );
                                },
                              ),

e caso presise da funcao getVoto() Future getVoto( int voto, String name) async { try { await FirebaseFirestore.instance .collection('votos') // Substitua 'nomes' pelo nome da sua coleção no Firestore .add( { 'voto': voto, 'nome': name }, ); print('Nome salvo com sucesso no Firestore!'); } catch (e) { print('Erro ao salvar nome no Firestore: $e'); } }

int voto = document.data()['voto'];
