Why I need this, or the use case that I want to use this properties.
-- I need empty property to seed a collection, in first run.
-- I also need size property to check the number of objects in a query result. for example, after a search I want to show number of total results, or I need to show number of unread notifications that user has.
are some properties and methods not exist in plugin? because I cannot found empty and size in source code also.
How can I get count for a query? or check if a collection is empty?
as mentioned in this doc, there is a size property in QuerySnapShot but it is undefined when trying to use.
