Configured The Default Firebase App __FIRAPP_DEFAULT

When following the flutter tutorial examples for adding firebase dependancies in the yaml file I would get this printout in the console "Configured the default Firebase app __FIRAPP_DEFAULT":

 dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^0.4.0+6
  cloud_functions: ^0.4.0+2
  firebase_auth: ^0.11.1+7
  firebase_database: ^3.0.3
  firebase_storage: ^3.0.2

In my particular workflow, when adding firebase dependencies, the tutorial code and flutter warnings never prompted to modify the AppDelegate.m file. It wasn't until I dialed back and added cloud_firestore did I get prompted with this warning:

6.3.0 - [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add [FIRApp configure]; (FirebaseApp.configure() in Swift) to your application initialization.

1. open xc workspace >> open ios/Runner.xcworkspace
2. open AppDelegate.m
3. in AppDelegate.m add the following line:

import Firebase;

4. in AppDelegate.m add the following snippet to your application did finish method

[FIRApp configure];

Here is what mine looked like in the end:
