title: Vue Router routes not tracked by Firebase Analytics
body: <p>I'd like to know if there's some configuration I might've missed when setting up Firebase Analytics for a Vue app (and for SPAs in general, I suppose) to get it to track page changes, because when I'm in Firebase's DebugView, it doesn't track <code>page_view</code>s unless I refresh the page or manually enter a URL into the browser. I know for the regular Google Analytics module (<code>vue-analytics</code>) you have to pass it the router object on initialisation for it to work (<a href="https://webdeasy.de/en/how-to-integrate-google-analytics-on-your-vue-js-page/" rel="nofollow noreferrer">more about that</a>) so it makes sense to me that you'd have to do something similar with Firebase Analytics, but I can't find anything in the docs about it.</p>
  
  <p>I've tried manually calling <code>logEvent('page_view')</code> from my <code>router.afterEach()</code> guard, but then it logs each page change multiple times.</p>
  
  <p>Please let me know if there's any info or demo code you'd like me to include.</p>
