You can visit Google Developer recommended training here Codelabs - Android

It is written on Java , but the idea is still there.

And you can quickly convert your code to Kotlin on Android Studio and study them later if your not familiar with Kotlin that much. From your Refactor menu (If I'm not mistaken for late version below 3.2.1).

From Firebase Docs don't forget to change the tab to Kotlin.

. If there is no Kotlin tab from the documentation, try the Firebase from your tool, and select the Realtime Database. It will show you the basic code. Since I'm using Java , it is showing Java code. Since your default lang is Kotlin, maybe it will show Kotlin code.
