Firebase notification style
<p>I use firebase with cURL. I wonder how to use big image style and put big image url to the "notification" section in json file.</p>

<p>My file looks like that:</p>

<pre><code>{
"to" : "my_device_id",

"notification" : {
  "body" : "great match!",
  "title" : "Portugal vs. Denmark",
  "icon" : "ic_notify",
  "click_action" : "FIREBASE_NOTIFICATION"
}
"data" : {
  "data1" : "data1_content"
}
}
</code></pre>

<p>I know how to put icon and click_action. I'm looking for keys for style and big picture content.</p>

<p><strong>EDIT:</strong></p>

<p>Ok, I just realized how looks firebase RemoteMessage.Notification class. There are no getters like "getBigPicture". It's probably impossible to do what I want, but I leave this question on account of firebase's newer versions (where they add this feature, I suppose.)</p>
