Flutter app not loading when I add Flutter_auth dependency - flutter

Question

Whenever I try to add the Flutter_auth dependency to my flutter application in the pubspec.yaml file, the app no longer is able to compile. The app however loads fine without the dependency. I have tried creating a fresh Flutter project, running it before adding the dependency, and it runs fine, however after adding the dependency, the app no longer compiles. Odd because I am not changing any lines of code in the actual app.
I am using visual studio code, and attached is a screen recording of the issue at hand. I tried adding the dependency manually, and through the terminal, neither allowed the app to compile. I have also tried running flutter clean in the terminal to clear any cache in the flutter dependencies section.
Please take a look at the screen recording for more details on the flutter version and which other dependencies I am trying to add. Screen Recording
I tried to run the flutter app as a project, running the main.dart file, and I expected the app to compile and launch the debug app, however when I added the firebase_auth dependency, the app no longer launched successfully. When I removed the dependency, the app compiled just fine. Without any changes to the code of the app.

Answer 1

Config app in firebase console, Download googleInfo-plist file to correct location.
Add initializeApp() method in void main():
import 'package:firebase_auth/firebase_auth.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
Check the installation steps on the start firebase documents and authentication to see if you are missing any steps
