title: How to reload a page on Navigation.pop in Flutter?
body: <p>I want to have page A reload, re-run the Http requests, once I pop back to it from another page that lets you edit the data page A displays. The other page is triggered by a long press in a ListView generated by a function within page A. IE:
  Page A:</p>
  
  <p>_PageAState</p>
  
  <ul>
  <li>Reload function I need to call</li>
  </ul>
  
  <p>Scaffold</p>
  
  <ul>
  <li><p>List item</p></li>
  <li><p>Text</p></li>
  <li>ETC...</li>
  <li>Expanded
  
  <ul>
  <li>ListView
  
  <ul>
  <li>Gesture Detector that navigates</li>
  </ul></li>
  </ul></li>
  <li>ETC</li>
  </ul>
  
  <p>How can I trigger a function of any sort or make the page reload when I pop back to it?</p>
  
  <p>I've tried passing data from the pop and using an if statement but the nested structure messes it up.</p>
