title: How do I create a "fake" dart:io File from in-memory bytes?
body: <p>I have the in-memory bytes of a "blob", but the API that I want to process this "blob" with only accepts dart:io File objects.</p>
  
  <p>Is there a way to create a "fake" dart:io File , simply wrapping my in-memory bytes, so that I can pass this "fake" File to my API?</p>
  
  <p>Assume that a file system doesn't exist, and assume that I can't write the in-memory bytes to a "real" file.</p>
  
  <p>Thanks!</p>
