Assign Firestore JSON object to a variable in Kotlin

Question

In my Firestore I have a "employee" node that looks like that :

I'm asigning that node to a "User" object in Kotlin:

object User {
    val firstName: String = "";
    val lastName: String = "";
    val employeeId:String="";
    val city:String = "";
    val email:String="";
    val salary:Number=0;
    val imgUrl:String="";
    val employmentStatus:String="";
    val employmentDate: ??????
}

My question is what type should "employmentDate" be? In Typescript I'm doing just:

employmentDate:{day:number,month:number,year:number}

can I do something similar in Kotlin?

Don't use object. object are singleton classes in kotlin. Instead use normal classes in kotlin and use composition.

class User{
val firstName: String = "";
val lastName: String = "";
val employeeId:String="";
val city:String = "";
val email:String="";
val salary:Number=0;
val imgUrl:String="";
val employmentStatus:String="";
var employmentDate: EmploymentDate = EmploymentDate()

class EmploymentDate{
val day:Int=0
val month:Int=0
val year:Int=0
}
}

You can store it in shared preferences or create a custom singleton class wrapper around it.

could You please clearified " custom singleton class wrapper around it" - like You said object is like a singeltone in kotlin so that's what I just did ,I put my User in a singeltone-guessing I am missunderstanding something here...:S

object MySingleton {     lateinit var myUser: User  } /* Somewhere after getting the data from the FireStore  */ MySingleton.myUser=user

After this you can access using your singleton class anywhere.
