Problema com future builder não recarrega a tela mesmo transformando em stateful

Fiz o código da mesma maneira que o curso. Ao finalizar o fomulário cadastra no banco. Mas, ao dar o pop não atualiza a tela mesmo seguindo a ideia de mudar pra statefulWidget. Só se abrir a tela novamente. No debug tbm não chama o método findall() Segue abaixo o código da contact_lista.dart

import 'package:flutter/material.dart';

class ContactsList extends StatefulWidget {
  @override
  State<ContactsList> createState() => _ContactsListState();
}

class _ContactsListState extends State<ContactsList> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Contacts'),
      ),
      body: FutureBuilder<List<Contact>>(
        initialData: List.empty(growable: true),
        future: findAll(),
        builder: (BuildContext context, AsyncSnapshot<dynamic> snapshot) {
          switch (snapshot.connectionState) {
            case ConnectionState.none:
              break;
            case ConnectionState.waiting:
              return Column(

              break;
            case ConnectionState.done:
              if (snapshot.hasData) {
                final List<Contact> contacts = snapshot.data;
                return ListView.builder(
