Realtime database emulator support

[b3nb5n]

I'm working on a project that uses the Realtime Database. In the past I've only ever used Firestore, and I'm used to connecting to the emulator by doing something like this immediately after initiating Firebase.

if (kDebugMode) {
    FirebaseFirestore.instance.settings =
        Settings(host: 'https://localhost:8080', sslEnabled: false);
}

However, I can't find anything like this for the Realtime Database, the closest I've come is doing this every time I need to access FirebaseDatabase.instance.

final host = kDebugMode ? 'http://localhost:9000' : 'http://10.0.2.2:9000';
final database = FirebaseDatabase(
  app: Firebase.app(),
  databaseURL: host,
);

Ideally I would only have to do this once when firebase is initialized, or something similar to the Cloud Functions emulator implementation FirebaseFunctions.instance.useFunctionsEmulator(origin: 'http://localhost:5000').
