I have quite a bit of data in Firebase Firestore that has its createdDate field saved as an ISO 8601 String (2024-05-15T18:08:30.825890). I did not have a need to perform any date comparisons before now but this is now a requirement for my application. The problem is, when I perform date comparison on the field for example var usersSnapshot = await FirebaseFirestore.instance.collection("users").where('dateCreated', isGreaterThan: dateCreated).get() I get 0 results. I suspect this is because the field in my firestore is saved with type string and not type timestamp.

In my document, I have an array of notes. Each note has the writer, the note text, etc. I wrote the notes using a class called Note. I would like to pull just the notes from the document and convert them into a List of Notes.
