Kotlin Companion Objection unresolved references

Question

I have a Kotlin class with companion object which sees some fields of the parent class and does not see others. There is no option in Android Studio to import.

class A{
   var a = 1
   var b = 2
       companion object {
            a += 1// visible and imported
            b += 1// unresolved reference
       }
}

I do not want to create this variable inside the companion object.

Answer 1

You are absolutely incorrect.

You cannot access members of class inside companion object at all. But you can use companion`s members in your class.

If you see kotlin bytecode you will see that Companion object compiles to

   public static final class Companion {
      private Companion() {
      }

      // $FF: synthetic method
      public Companion(DefaultConstructorMarker $constructor_marker) {
         this();
      }
   }

Since Companion is static class it can exist without class where it is declared.

So in your case you can not access a and b because probably they are not exists.

They are not accessable for you too, but probably you cought IDE bug and it doesnt give you error
