title: Flutter: can I mix Firebase Auth with Mongodb Databases?
body: <p>I must mention that I have no prior experience in backend development, and I know that questions on the subject have been asked before but I need a specific answer to this one.</p>
  <p>I was wondering if I could use Firebase authentication to register &amp; sign in my users and store their data in Mongodb?</p>
  <p>If so, what am I supposed to learn besides &quot;firebase_auth&quot; and a Mangodb package to make it work?</p>
