Is the not equals cloud firestore query functionality available for flutter plugin? [closed]

Question

So at the start of this month, the firebase team announced here that the not equals queries are now available but I am not able to find if this is something I can use in flutter as well. If yes, could you please provide the syntax?

Thanks.

Update Nov 6, 2020:

cloud_firestore 0.14.3 now supports != queries using isNotEqualTo as seen in the API documentation for where(). If you are using an old version, you will have to upgrade.

Original answer:

Firestore's inequality queries are currently not supported in Flutter. If they were, you would see it in the API documentation for the where method. It would also necessitate an update of the written documentation on query limitations, where it currently says:

Cloud Firestore does not support the following types of queries:

Queries with a != clause. In this cause, you should split the query into a greater-than query and a less-than query. For example, the query clause where("age", isNotEqualTo: 30) is not supported, however you can get the same result set by combining two queries, one with the clause where("age", isLessThan: 30) and one with the clause where("age", isGreaterThan: 30)

The GitHub issue tracking this update is here: https://github.com/FirebaseExtended/flutterfire/pull/3748

As of Nov 4, the update is merged and should appear in a future release described in the release notes.
