How Firebase Works Internally on Flutter Dependencies - firebase

Question

Currently, I use Firebase in the Flutter project. Firebase Analytics library in detail.
However, I became curious when I used this library.
Firebase Analytics's services operate automatically without any method calls from the entry point.
All I have to do is add the dependencies of the project as follows:
dependencies:
firebase_analytics: ^8.3.1
I don't know what procedures this is internally activated and moved by.
Can any experts explain how this is possible internally?

calls from the entry point.

dependencies:
firebase_analytics: ^8.3.1
That is not correct as there are a couple more processes to set it up.
Here is the step from the package's documentation:
To use this plugin, add firebase_analytics as a dependency in your pubspec.yaml file.
You must also configure firebase analytics for each platform project: Android and iOS.
You need to add the FirebaseAnalytics object and the FirebaseAnalyticsObserver object to the MaterialApp:
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
static FirebaseAnalytics analytics = FirebaseAnalytics();
static FirebaseAnalyticsObserver observer =
FirebaseAnalyticsObserver(analytics: analytics);
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Firebase Analytics Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
navigatorObservers: <NavigatorObserver>[observer],
home: MyHomePage(
title: 'Firebase Analytics Demo',
analytics: analytics,
observer: observer,
),
);
}
}
The FirebaseAnalyticsObserver creates a NavigatorObserver that sends events to FirebaseAnalytics.
