How to retrieve documents form firebase firestore according to a specific value in those documents in flutter?

I have the following structure on firestore, enter image description here and I want to retrieve series documents that have the same category or genre (10 docs at a time).

EX: 10 series documents of category Mystery

I know it's done using the where() and limit() methods, but I don't know how to access the objects in the categories array especially when they have no names.

Currently, you cannot search for nested items within nested lists, you can however search for the exact object in the list, and in your case it's a Map<String, String>.

So, use this, which might\should work:

.where('categories', arrayContains: {"ar_title": غموض, "en_title":"Mystery"})
