My opinion is fetch the document and delete the item at which index you want from the local array and update the remote document. Or you can use .document('docID').updateData('cars': FieldValue.arrayRemove([{the-item-map}]));. Maybe there are other options but these two options are acceptable, I prefer to use first one.
