title: How to get query parameters value from deep link while dynamic link created using AppInvitation class using Firebase?
body: <p>In my app, I am sending invitation to people to join my app. I am using AppInvitation IntentBuilder Class to create Intent. After these steps, one URL-link gets generated that we can send to invitees.</p>
  
  <p>I have written below code to generated that link and start the activity to send the link. I am able to send invites and able to successfully launch the app by clicking the dynamiclinks. Both the dynamically and manually created ones.</p>
  
  <pre><code>IDictionary&lt;string, string&gt; values = new Dictionary&lt;string, string&gt;();
  
          values.Add("utm_campaign", "Health");
           values.Add("utm_medium", "GoIbibo");
           values.Add("ad", "1");
           values.Add("credit", "50");
           values.Add("utm_source", "Yahoo");
           values.Add("afl", "https://www.facebook.com");
  
          var intentbuidl = new AppInviteInvitation.IntentBuilder(MainActivity.mainActivity.GetString(Resource.String.invitation_title))
                           .SetMessage(MainActivity.mainActivity.GetString(Resource.String.invitation_message))
                           .SetDeepLink(Android.Net.Uri.Parse(MainActivity.mainActivity.GetString(Resource.String.invitation_deep_link)))
                           .SetAdditionalReferralParameters(values)
                           .Build();
  
          MainActivity.mainActivity.StartActivityForResult(Intent.CreateChooser(intentbuidl, "Install"),0);
  </code></pre>

  <p>So my question is, when do invitees open the app using this link? Can we be able to get these additional parameters which I have set using IDictionary from the above generated link?</p>
