title: How can I manually trigger a screen_view event in Firebase
body: <p>Currently we're using Firebase in our iOS app.</p>
  
  <p>I'm curious wether it is possible (and valid) to disable automatic reporting (using <code>FirebaseScreenReportingEnable</code>) and to call <code>Analytics.logEvent</code> (with the required params) manually.</p>
  
  <p>Something in the lines of </p>
  
  <pre><code>Analytics.logEvent("screen_view", parameters: [
    "firebase_event_origin": "auto",
    "firebase_previous_class": "PrevClass",
    "firebase_previous_id": "1",
    "firebase_previous_screen": "PrevScreen",
    "firebase_screen": "NewScreen",
    "firebase_screen_class": "NewClass",
    "firebase_screen_id": "2",
  ])
  </code></pre>
