title: Custom icons with react navigation 5
body: <p>I am trying to use custom icons with a react tabbar navigation. However, all the tutorials and docs
  always just cover implementing icons by Ionicons or Materialdesign. Is there a way I can implement my own Icons?</p>
  
  <p>This is how the code looks like atm:
  </p>
  
  <pre><code>&lt;Tab.Navigator tabBarOptions={{
    inactiveTintColor: '#707070',
    activeTintColor: 'red',
    style: {
      backgroundColor: '#F1F1F1',
      height: 60,
      color: 'red',
      paddingBottom: 5
    }
  }}&gt;
    &lt;Tab.Screen name="Bestellungen" component={BestellungenOverview}/&gt;
    &lt;Tab.Screen name="Kunden" component={KundenOverview} /&gt;
    &lt;Tab.Screen name="Zahlungen" component={ZahlungenOverview} /&gt;
    &lt;Tab.Screen name="Statistiken" component={StatistikenOverview} /&gt;
    &lt;Tab.Screen name="Einstellungen" component={Einstellungen} /&gt;
  &lt;/Tab.Navigator&gt;
  </code></pre>
  
  <p></p>
