title: Is there a way to batch read firebase documents
body: <p>I am making a mobile app using flutter with firebase as my backend.</p>
  
  <p>I have a collection of user document that stores user information. one of the fields is an array of references (reference documents in another collection) which I want to use in an operation like batch that in that would then allow be to read all the documents.</p>
  
  <p>I know batch only allows writes to the database, My second option would be Transaction, which requires writes after reads which I am trying to avoid.</p>
  
  <p>Is there a way to read multiple documents in one operation without having to use Transaction?</p>
