The pattern Singleton in Kotlin is designed by object, so if in java to get an instance of the singleton while we create it : public static SingletonClass getInstance(param1, param2, ...) which will initialize some var "Dynamicly" in the SinletonClass and in the same time create the instance using this params, and as we know there is no constructor in kotlin objects, so how do i pass my params to the object dynamicly ?

You cannot

You can't. If you really want an

object

then you could make it wrap a regular

class

and add something like

fun initialize(…)

to your

object

which sets up the wrapped

class

instance. Anytime you access the

object

you throw an exception if

initialize

wasn't called yet.

also a side note, I believe this is a very bad anti-pattern
