Pagina não é atualizada após de inclusão de item

Também estou com o mesmo problema. Percebi que ao salvar o contato, o builder do FutureBuilder do ContactsList é executado com o snapshot.connectionState == donne. Até aí sem problemas. Porém percebi que em nenhum momento o findAll é executado novamente para trazer o novo registro da tabela contacts. Ou seja, ele carrega a lista como era anteriormente e por isso sem o novo contato.

import 'package:bytebankbd/database/dao/contact_dao.dart';
import 'package:bytebankbd/models/contact.dart';
import 'package:flutter/material.dart';

import 'contact_form.dart';

class ContactsList extends StatelessWidget {

  final ContactDao _dao = ContactDao();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Contacts'),
      ),
      body: FutureBuilder<List<Contact>>(
        initialData: List(),
        future: _dao.findAll(),
        builder: (context, snapshot) {
          switch (snapshot.connectionState) {
            case ConnectionState.none:
              break;
            case ConnectionState.waiting:
              return Center(
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center,
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: <Widget>[
                    CircularProgressIndicator(),
                    Text('Loading'),
                  ],
                ),
              );
              break;
            case ConnectionState.active:
              break;
            case ConnectionState.done:
              final List<Contact> contacts = snapshot.data;
              return ListView.builder(
                itemBuilder: (context, index) {
                  final contact = contacts[index];
                  return _ContactItem(contact);
                },
                itemCount: contacts.length,
              );
              break;
          }
          return Text('Unknown error');
        },
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          Navigator.of(context).push(
            MaterialPageRoute(
              builder: (context) => ContactForm(),
            ),
          );
        },
        child: Icon(Icons.add),
      ),
    );
  }
}

class _ContactItem extends StatelessWidget {
  final Contact contact;

  _ContactItem(this.contact);

  @override
  Widget build(BuildContext context) {
    return Card(
      child: ListTile(
        title: Text(
          contact.name,
          style: TextStyle(fontSize: 24.0),
        ),
        subtitle: Text(
          contact.accountNumber.toString(),
          style: TextStyle(fontSize: 16.0),
        ),
      ),
    );
  }
}

O mesmo está acontecendo comigo, bem frustrante.
