Not Finding and Deleting a Firebase Document - firebase

Question

I am trying to make a form so that whenever you enter information and press a button, it will delete an item from the firebase database. I got the addUser code working, but when I got to the deleteUser, it compiles fine but then whenever I submit a form it doesn't show that I deleted it. I know I am putting in the same data exactly, so I think the problem is either the async in my function title or the await in my itemsSnapshot, but I have no idea since deleting a document this way is super weird. What am I doing wrong? (I am not including the imports because I'm not sure if that is sensitive data)

const AdminScreen({Key? key}) : super(key: key);
#override
State<AdminScreen> createState() => _AdminScreenState();
}
class _AdminScreenState extends State<AdminScreen> {
CollectionReference items = FirebaseFirestore.instance.collection('items');
reloadUser() {
setState(() {});
}
//this section is for adding stuff to database
String name = "";
String type = "";
String location="";
String imageURL = "";
String claimed = "false";
bool addDataVisible = true;

TextEditingController deleteLocationController = TextEditingController();
Object addUser() {
// Call the user's CollectionReference to add a new user
if(name!="" && type!="" && location!="") {
return items
.add({
'name': name,
'type': type,

Future<Object> deleteUser() async{
var itemsSnapshot = await items.get();
// Call the user's CollectionReference to add a new user

for (var document in itemsSnapshot.docs) {

document[type] == deleteType &&

items.doc(idDelete).delete();
print("user deleted success");
