title: app receives different push notification structure on emulator and when prod build installed on real device iOS Flutter
body: <p>I am sending push notification to iOS using <a href="https://pub.dev/packages/firebase_messaging" rel="nofollow noreferrer">https://pub.dev/packages/firebase_messaging</a>. When run-in gin emulator I receive push notification with notification object notification&quot;:{&quot;body&quot;:&quot;Test&quot;,&quot;title&quot;:&quot;Test&quot; }, however when app is built and deployed I receive same title in &quot;app&quot;: {&quot;alert&quot;: {&quot;title&quot;: &quot;test&quot;} }</p>
  <p>It is deployed on Apple 6 but iOS 13.</p>
  <p>This behaviour looks similar to message[&quot;data&quot;] ?? message however not mentioned anywhere in docs.
  How should I behave? Should I add same check or it is a bug?</p>
  <p>Also body property is missing...</p>
