title: Listview of stateful widgets
body: <p>I would like to build a list with ListView.builder of stateful widget.</p>
  
  <p>I am building a social network app and I have a list of posts.
  Every post has a like button so when I press it, it should be updated in every screen.</p>
  
  <p>So I would like to wrap every post (that is an item in the listview) in a post bloc that can handle the like operation and update itself accordingly.</p>
  
  <p>I don't know if this can be an heavy pattern and if the list will somehow make explode the smartphone of the users.</p>
