My question is not related to Kotlin? 😮

https://kotlinlang.org/docs/tutorials/android-plugin.html i am trying view binding in a fragment and it doesnt seem to work the way it does for an activity

Would I have any problem/drawback calling an activity on an companion object like that? Memory Leak or something like that?

companion object {
     
        fun start(context: Context) { 
        launch{
            if (context.prefs.fooProperty) //ext fun on shared pref{
                val intent = Intent(context, Foo::class.java)
                context.startActivity(intent)
            }
         }
        }
    }
