title: Flutter push notifications with JSON body
body: <p>I have an flutter app with backend symfony(php), the app is integrated with firebase, and in the notification body i receive JSON something like:</p>
  <pre><code>body: {&quot;token&quot;:&quot;4243453&quot;,&quot;title&quot;:&quot;Store&quot;,&quot;price&quot;:50,&quot;currency&quot;:&quot;GPB&quot;}
  </code></pre>
  <p>I have tried to pars the data, but with no luck, my question is, is that possible in flutter to pars json data in the notification body, or that needs to be done by the backend ?</p>
