title: How to access multiple streams inside a StreamBuilder?
body: <p>I've tried to make a new <code>StreamBuilder</code> inside the builder of my initial stream, and while I don't get any errors, it also doesn't seem like it works. Is this possible to do?</p>
  <p>Basically, I'm accessing a root Collection in Firebase. This collection contains two documents, and I need data from each of them, as I am building a DataTable that contains information from both paths.</p>
  <p>EDIT: The nested StreamBuilder doesn't work because StreamBuilder must return a widget, so at least I know why it wasn't working. But I still don't have a resolution on what to do.</p>
