title: Firebase Dynamic Links - how to send additional data inside the link?
body: <p>I'd like to create a deep link using Firebase Dynamic Links.</p>
  
  <p>I have read the documentation and in order to create the deep link using REST API, 
  one need to create HTTP POST request with a JSON object as the following:</p>
  
  <pre><code>{"dynamicLinkInfo": 
  {
  "dynamicLinkDomain": "abc123.app.goo.gl",
  "link": "https://example.com/",
  "androidInfo": {
    "androidPackageName": "com.example.android"
  },
  "iosInfo": {
    "iosBundleId": "com.example.ios"
  }
  }
  </code></pre>
  
  <p>My question is - I'd like to send additional data to the application, inside the link. How can I do it?
  Thanks!</p>
