Hello!
I need to make an appointment with filter on firestore
but I read in the documentation that they do not have "!=" or "Isnotiqualto" to create a restriction. I wanted to do something like:
Search for books that are not registered with the user’s email.
var snapshots = Firestore.instance
.collection('livros')
.where('email', isNotEqualTo: _email )
.snapshots();
Does anyone have any suggestions?
is not possible according to documentation, it follows: https://firebase.google.com/docs/firestore/query-data/queries?hl=pt-br#query_limitations
