title: Receive share file intents with Flutter
body: <p>I searched for a way to make my flutter app receive intents from other apps, but didn't find any.</p>
  
  <p>I want to <strong>RECEIVE INTENTS</strong> not to send them.</p>
  
  <p>example:</p>
  
  <p>I want to open the Gallery and click on the share button, and choose my flutter app from the menu. and then have my flutter app receive the intent with the picture (and later send it by HTTP request).</p>
  
  <p>Does anyone know how to do it?</p>
