How can I filter from the map in the document?

How can I filter from the map in the document?

my query function;

      ref
        .where('tag_id', isEqualTo: item)
        .where('likes', arrayContains: {
          Get.find<AuthController>().getCurrentUser!.uid: true
        })
        .orderBy('created_date', descending: true)
        .orderBy('like_count', descending: true)
        .orderBy('comment_count', descending: true)
        .limit(max.value)
        .get();

I want to filter on 'likes' map. I tried to make an example in the code below, but no data is coming. map in document

map in document

returning null

Your likes is not an array, so array-contains won't work on it.

What you're looking for is :

const uid = Get.find<AuthController>().getCurrentUser!.uid;
ref
  .where('tag_id', isEqualTo: item)
  .where('likes.$uid', isEqualTo: true)

For more on this dot notation, see the Firebase documentation on updating fields in nested objects.
