I store an id(nanoid) and email as fields of userinfo document. But when I retrieve userinfo all other fields like name, phone,are returned but id and email returned null. When I look through the console id and email fields have data (they are not null) but when I retrieve them through streambuilder they are returned null. Also in all other documents that have id and email fields they are returned null while they have data when I look through the console. help please.
