So i’m getting the obvious error of undefined name

CloudNote.fromSnapshot(QueryDocumentSnapshot<Map<String, dynamic>> snapshot)
firstName = snapshot.data()[firstNameFieldName] as String;
lastName = snapshot.data()[lastNameFieldName] as String;

I know the painful option of manually adding the field but…..last resort.

Strange that the Firestore Database doesn’t allow you to select all documents in your collection and add fields to all of them.

You could try something like this

 Future<void> addFirstNameLastName(
  {required String ownerUserId,
  required String firstName,
  required String lastName}) async {
try {
  await notes
      .where(
        ownerUserIdFieldName,
        isEqualTo: ownerUserId,
      )
      .get()
      .then((value) => value.docs.forEach((doc) {
            doc.reference.update({
              firstNameFieldName: firstName,
              lastNameFieldName: lastName,
            });
          }));
} catch (e) {
}}

That's a good point, I think Firebase/Google are working on that feature. It is a little odd that they have only implemented delete functionality. But try the code above in your FirebaseCloudStorage class. Assign it to a button

void addFirstNameLastName(
  {required String ownerUserId,
  required String? firstName,
  required String? lastName}) async {
try {
  await notes
      .where(
        ownerUserIdFieldName,
        isEqualTo: ownerUserId,
      )
      .get()
      .then((value) => value.docs.forEach((doc) {
            doc.reference.set({
              firstNameFieldName: '',
              lastNameFieldName: '',
            }, SetOptions(merge: true));
          }));
} catch (e) {
  throw (CouldNotGetAllNotesException());
}}

Adding a - update function in FirebaseCloudStorage class

Calling the class when button is tapped.
