[cloud_firestore] isEqualTo matches against null

[kroikie]

QuerySnapshot _query = await someCollection
        .where('field1', isEqualTo: value1)
        .getDocuments();

this will match a doc even when value1 in the query is null, but in the doc itself it's populated. likewise when you string together multiple isEqualTo statements. it just returns everything in the collection.

This is a "non-issue" as is working as intended.

To query against null values, use the isNull filter:

QuerySnapshot _query = await someCollection
        .where('field1', isNull: true)
