title: FCM support when app is terminated
body: <p>I am using FCM notification for my app. When my app is in background or foreground I am receiving notification. But when my app is terminated that means closed from task then I am not receiving any notification. I searched about this and I am confused is it work when the app is terminated? I just need to know is it work or not when the app is terminated.</p>
  
  <p>If it works when the app is terminated then I will go for next step for my app otherwise I will stop my implementation that's why I am not sharing any code. I followed <a href="https://firebase.google.com/docs/cloud-messaging/ios/receive" rel="nofollow noreferrer">this link</a></p>
