How to assign same name Class variable in kotlin?

Question

I want to assign my context in constructor but when I use "this" ide warn me. How can I write code like this Java code below, but in Kotlin:

here is java code

public class LoginApiService {
    Context context;

    public LoginApiService(Context context) {
        this.context = context;
    }
}

here is what I want to do

class YLAService {


var context:Context?=null

class YLAService constructor(context: Context) {
    this.context=context
}

}

it isn't clear what you are trying to do, you should show the Kotlin code so we can see the final intent. And any warning/error you are having. — Jayson Minard

In Kotlin, if you provide a var or val in the constructor, it automatically becomes available as a property you can use. No other assignment is required.

class LoginApiService(val context: Context) {

   // Example...
   fun doSomething() {
      context.doSomethingOnContext()
   }
}

you could provide an example with constructor keyword

using the constructor keyword for no reason is not idiomatic, what @todd presented is typical code.

I edit my question and I need to write something inside my constructor.
