问题
I want to make a Flutter app for showing shop details. I stored data in the Firestore real-time database. It's working perfectly.
What I want to do now is make another app for the owner, then he can change data in Firestore and also send push notifications to shop app users.
Is this possible? It would be helpful If you have any tutorials or videos.I haven't tried cloud functions because they need a credit card, Which I don't have.
