No Firebase App has been created

[AleFachini]

I copied the whole code and i get this error.

The following FirebaseException was thrown building GetMaterialApp: [core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()

Did i miss something?

There was a big Firebase update, most of my example code doesn't really work with firebase. But there is a guide on how to update, that is pretty easy to follow. You can find it at https://firebase.flutter.dev/docs/overview#initializing-flutterfire
