You can wrap the whole host choosing part for the Android emulator in an assert block to remove it from the production build automatically.

  // Wrap in assert with an anonymous function that returns true to exclude it from production
  assert((() {
    // If on Android emulator, don't use localhost
    String host = Platform.isAndroid ? '10.0.2.2:8080' : 'localhost:8080';
    FirebaseFirestore.instance.settings = Settings(
      host: host,
      sslEnabled: false,
      persistenceEnabled: false,
    );

    return true;
  })());

I don't know if I missed a step, but the "Additional Superpowers" code snippets are invalid. For example, the analytics needs to be initialized, and the "automatic traces" for performance give an issue with unused import, etc.

This snippet seems to "fix" the analytics initialization:

import 'package:firebase_analytics/firebase_analytics.dart';

FirebaseAnalytics? analytics;

void main() {
  analytics = FirebaseAnalytics.instance;
  runApp(const MyApp());
}

(Below applies to: Flutter 3.3.2, Google Services 4.3.3, and Firebase-Crashlytics-Gradle 2.9.0, as well as minSdkVersion 21 in your 'app-level' build.gradle)

For simplicity, I call both the Firebase Analytics and Firebase Crashlytics via their own method:

Future<void> initializeFirebaseLytics() async {
    FirebaseAnalytics.instance;
    FlutterError.onError = FirebaseCrashlytics.instance.recordFlutterFatalError;
}

The above can be successfully called only after Firebase initialization is successful (so, like once "snapshot.connectionState == ConnectionState.done" is true). If you're having issues with initializing any of the above - here's my entire main.dart:

import 'package:firebase_crashlytics/firebase_crashlytics.dart';
import 'package:firebase_analytics/firebase_analytics.dart';
import 'package:firebase_core/firebase_core.dart';
import 'firebase_options.dart';

void  main() {
    WidgetsFlutterBinding.ensureInitialized();
    runApp(const  App());
}

class  App  extends  StatefulWidget {
    const  App({super.key});

    @override
    State<App> createState() => _AppState();
}

class  _AppState  extends  State<App> {
    final  Future<FirebaseApp> _initialization = Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
);

   @override

   Widget  build(BuildContext  context) {
	   return  FutureBuilder(
		   future: _initialization,
		   builder: (context, snapshot) {
			   if (snapshot.hasError) {
				   return  const  Text('error');
			   }
			   if (snapshot.connectionState == ConnectionState.done) {
				   initializeFirebaseLytics();
				   return  MaterialApp(
					   routes: appRoutes,
					   theme: appTheme,
				   );
			    }
			    return  const  Text('loading');
			 },
		);
    }
}

Future<void> initializeFirebaseLytics() async {
    FirebaseAnalytics.instance;
    FlutterError.onError = FirebaseCrashlytics.instance.recordFlutterFatalError;
}
