Why am I getting a Bad state error in this case?

[VitorFreitass]

I updated all my packages to the latest version and now I'm getting this error: Bad state: field does not exist within the DocumentSnapshotPlatform when fetching some data.

I found some issues related to the same problem here but none solved my problem, most of them were related to changes on how DocumentSnapshot works and I probably must have missed something from the documentation that is causing this error.

Well, I'll put below where I think the problem is and the complete code.

I think the problem is here

List<UserResult> searchResults = [];
     snapshot.data.docs.forEach((doc) {
      Users user = Users.fromDocument(doc);
      UserResult searchResult = UserResult(user);
      searchResults.add(searchResult);
    });

Things I've tried and it didn't work

1:

List<UserResult> searchResults = [];
   snapshot.data().docs.forEach((doc) {
   Users user = Users.fromDocument(doc);
   UserResult searchResult = UserResult(user);
   searchResults.add(searchResult);
  });

2:

 List<UserResult> searchResults = [];
      var item = snapshot.data();
       item.docs.forEach((doc) {
       Users user = Users.fromDocument(doc);
       UserResult searchResult = UserResult(user);
       searchResults.add(searchResult);
     });

3:

 List<UserResult> searchResults = [];
       snapshot.data.docs.forEach((doc) {
       Users user = Users.fromDocument(doc.data());
       UserResult searchResult = UserResult(user);
       searchResults.add(searchResult);
     });

For understanding

class _SearchState extends State<Search> {
      TextEditingController searchController = TextEditingController();
      Future<QuerySnapshot> searchResultsFuture;
    
      handleSearch(String query) {
          Future<QuerySnapshot> results =
              usersRef.where("tag", isEqualTo: query).get();
    
          setState(() {
            searchResultsFuture = results;
          });
      }
    
      buildResults() {
        return FutureBuilder(
          future: searchResultsFuture,
          builder: (context, snapshot) {
            if (snapshot.connectionState != ConnectionState.done) {
              return SizedBox(
                  child: CircularProgressIndicator(),
                );
            }
            List<UserResult> searchResults = [];
            snapshot.data.docs.forEach((doc) {
              Users user = Users.fromDocument(doc);
              UserResult searchResult = UserResult(user);
    
              searchResults.add(searchResult);
            });
            return SingleChildScrollView(
              child: Column(
                children: searchResults,
              ),
            );
          },
        );
      }
    
      buildNoContent() {
        return Container();
      }
    
      @override
      Widget build(BuildContext context) {
        return Scaffold(
            body: Container(
                child: SingleChildScrollView(
                  child: Column(
                    children: <Widget>[
                      Center(
                        child: Text(
                            "Type something",
                          ),
                        ),
                      TextFormField(
                        enableInteractiveSelection: true,
                        controller: searchController,
                        keyboardType: TextInputType.text,
                        onFieldSubmitted: handleSearch(searchController.text),
                      ),
                      
                      searchResultsFuture == null
                          ? buildNoContent()
                          : buildResults(),
                    ],
                  ),
                ),
          ),
        );
      }
    }
