Answer 1

The answer by @Peter Haddad is correct. Just to highlight the difference with an example from my own code:

The previous version of code which created the same error:

snapshot.data.docs[index].data["chatRoomID"]

Updated version of code which solved the error:

snapshot.data.docs[index].data()["chatRoomID"]
