title: how to update just one item in recyclerview with listAdapter(using diffUtil)
body: <p>I have a recyclerview using listAdaper.this recyclerview has so many Items(this is chat list).<br />
  if i edit a particular item of list , DiffUtil compare all of the items of the  newlist and old list. it takes long time so updating the  list has delay;<br />
  is there any way to restrict the Diffutil to compare just particular item?</p>
