If I use a String as argument on a Provider the return of a Provider work But If I use a List

just like instagram my application has a feature that are the saved. One person can save post. For this I added a field in the users collection "save", this field is an array of "post id". This "post id" is used to fetch recipes (another collection) A user, if you want to see the posts you saved, click on a button and you are directed to this widget: ("getReceitaGuardadosProvider"-> this is the provider that I m talking about) receita=ref.read(getReceitaGuardadosProvider(user.guardados)); So if I give this provider a String as a argument It will return AsyncData(), but If I give a List as a argument It will return AsyncLoading()

import 'package:chefapp/features/auth/controleer/auth_controller.dart';
import 'package:chefapp/features/receita/receitas_controller/receitas_controller.dart';
import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:chefapp/core/common/loader.dart';
import 'package:chefapp/core/common/error.dart';

import '../../models/teste.dart';
import '../receita/receita_screen.dart';

class GuardadosPerfil extends ConsumerWidget {
  const GuardadosPerfil({
    Key? key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    final user = ref.watch(userProvider)!;
//final receitaa = //ref.read(getReceitaGuardadosProvider(user.guardados));
//print('receita');
    //print(receitaa);
    //print(user.guardados);
    return Scaffold(
      appBar: AppBar(
        title: const Text('Receitas Guardadas'),
      ),
      
      body: ref.read(getReceitaGuardadosProvider(user.guardados)).when(
            data: (data) {
              return ListView.builder(
                itemCount: data.length,
                itemBuilder: (BuildContext context, int index) {
                  final receita = data[index];
                  return ReceitaScreen(
                      receita: receita, usermodel: user, aux: true);
                },
              );
            },
            error: (error, StackTrace) {
              return ErrorText(error: error.toString());
            },
            loading: () => const Loader(),
          ),
    );
  }
}

Here is a controller Controller.dart

    import 'package:chefapp/core/providers/storage_repository_provider.dart';
import 'package:chefapp/features/auth/controleer/auth_controller.dart';
import 'package:chefapp/models/receita_model.dart';
import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:routemaster/routemaster.dart';
import 'package:uuid/uuid.dart';
import 'dart:io';
import '../../../core/utils.dart';
import '../../../models/coment_model.dart';
import '../../../models/teste.dart';
import '../../../models/usermodel.dart';
import '../receita_repository/receita_repository.dart';

final receitaControllerProvider =
    StateNotifierProvider<ReceitaController, bool>((ref) {
  final receitaRepository = ref.watch(receitaRepositoryProvider);
  final storageRepository = ref.watch(storageRepositoryProvider);
  return ReceitaController(
      receitaRepository: receitaRepository,
      ref: ref,
      storageRepository: storageRepository);
});

  final getReceitaGuardadosProvider = StreamProvider.family<List<Receita>, List<String>>(
  (ref, guardados) {
    print('ola');
    final receitaController = ref.watch(receitaControllerProvider.notifier);
    return receitaController.getReceitaGuardados(guardados);
  },
);


class ReceitaController extends StateNotifier<bool> {
  final ReceitaRepository _receitaRepository;
  final Ref _ref;
  final StorageRepository _storageRepository;
  ReceitaController({
    required ReceitaRepository receitaRepository,
    required Ref ref,
    required StorageRepository storageRepository,
  })  : _receitaRepository = receitaRepository,
        _ref = ref,
        _storageRepository = storageRepository,
        super(false);
  
  Stream<List<Receita>> getReceitaGuardados(List<String> guardados) {
    print('controller');
    print(_receitaRepository.getReceitaGuardados(guardados));
    return _receitaRepository.getReceitaGuardados(guardados);
  }
} 

Here is a repository.dart

import 'package:chefapp/core/constants/firebase_constants.dart';
import 'package:chefapp/core/failure.dart';
import 'package:chefapp/models/usermodel.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:fpdart/fpdart.dart';
import '../../../core/providers/firebase_providers.dart';
import '../../../core/type_defs.dart';
import '../../../models/coment_model.dart';
import '../../../models/receita_model.dart';

final receitaRepositoryProvider = Provider((ref) {
  return ReceitaRepository(
    firestore: ref.watch(firestoreProvider),
  );
});

class ReceitaRepository {
  final FirebaseFirestore _firestore;

  ReceitaRepository({required FirebaseFirestore firestore})
      : _firestore = firestore;

  CollectionReference get _receitas =>
   _firestore.collection(FirebaseConstants.receitasCollection);

  CollectionReference get _users =>
      _firestore.collection(FirebaseConstants.usersCollection);

  CollectionReference get _comments =>
   _firestore.collection(FirebaseConstants.commentsCollection);

  Stream<List<Receita>> getReceitaGuardados(List<String> guardados) {
    return _receitas
        .where('id', whereIn: guardados)
        .orderBy('datacriacao', descending: true)
        .snapshots()
        .map(
          (event) => event.docs
              .map(
                (e) => Receita.fromMap(
                  e.data() as Map<String, dynamic>,
                ),
              )
              .toList(),
        )
       .map((list) {
        print('repository');
        print(list); // Adicione este print para imprimir a lista
     return list;
      });
  }
}

All the print that I use seems to be alright. I really don't know what can I do. If I change the function to accept a String I can print the recipe but only one, If I use a List the loading: () => const Loader() is the only thing I see.

some output of the prints Instance of '_MapStream<List, List>'

AsyncLoading<List>()
