How to implement firebase analytics in android application efficiently?

Question

Good day, I have been working on an android project for last 3 months. As time passes project grows big, but now I need to implement Firebase Analytics into the project, to track every app screen and event as well. But I found out that, using the basic implementation again and again for every onClick methods or classes in my project and custom events as well doesn't worth much. I need an efficient/generic way to implement it. Let me know if you can help this me out.

What I checked already:

Firebase Analytic Official doc
Implement analytics efficiently

I also found this blog which illustrates to implement it using KotlinPoet (As I'm using Kotlin with MVVM pattern for the development), AnnotationProcessor and EventBus and some other libraries. But I don't found it useful (Cz, just for the analytics I had to work a lot and put those annotations for every classes as well).

So, I want to know the best practice and efficient way to implement it into my large project easily. Any kind of help will be appreciable. Thanks for your time.
