I have a question of Kotlin coding style. I usually put companion object on the top of class layout. Because it made me easy to find const value that I set in companion object. But Kotlinlang.org suggest us to put companion object on bottom of class layout. I wonder why suggestion is like that. Dose it have any reason ? https://kotlinlang.org/docs/coding-conventions.html#class-layout

yeap because inner class/objects should be bottom of the class, it is due to this, it seems not right to you probably you just have some constant values there, like Java’s

private static final x

but in kotlin you are wrapping it with and object called

companion object

so that’s the reason 🙂

yes, no need to put them in a companion object unless that's how you want to expose it to other users
