              .snapshots(),
          builder: (context, snapshot) {
            if (snapshot.data == null)

                            ),
                          ],
                        )
                      ],
                    ),
                  ),
                ),
              ),
            );
          },
        ));
  }
}

Change lenght to length

That's a typo i think. If you wondering why length . That's because you are trying to get the length of snapshot.data.documents and initialise it to itemCount to allow the list to loop your item. I hope this solution works for you.
