Notifications

[dwu359]

Is your feature request related to a problem? Please describe.
The app should notify users whenever new stories are out. Users should also have the option to enable/disable notifications (likely in the Drawer). Tapping on a notification should redirect the user to the specified article.

Describe the solution you'd like
Look into Firebase Cloud Messaging (https://firebase.flutter.dev/docs/messaging/notifications/)

Describe alternatives you've considered
We could use a custom notifications server to remove collisions from notifications (multiple notifications containing the same article), but it's probably more complicated to do that and would take more $$$
