Switching between multiple Firebase projects/environments in Flutter?

Question

Has anyone figure out how to switch Firebase project/environments inside the app, say you had a drop down with different dev URLs. We are not talking about different builds, that won't work for us and would require sending multiple versions to TestFlight.

There's a snippet of code we found here.

final options = FirebaseOptions.from({});
final firebaseApp = await FirebaseApp.configure(name: 'some_app_name', options: options);

But we can't figure out how to use it, and don't know if it works correctly.

Edit

It was not officially supported when I wrote this. It now is.

      apiKey: 'AIzaSyArgmRGfB5kiQT6CunAOmKRVKEsxKmy6YI-G72PVU',
      projectID: 'flutter-firestore',
    ),
  );
  final Firestore firestore = Firestore(app: app); // this line is imp

Use firebase core package for it to work, https://pub.dev/packages/firebase_core For more info: https://firebase.google.com/docs/projects/multiprojects#node.js
