Empty constructor for kotlin object to use Firebase

I'm trying to save an object inside Firebase database from Kotlin,
I dont feel right providing a default empty constructor and put values as

, having to change all my code bc of this.

My class:

class Video(var id: String, var url: String, var owner: User) : {
constructor() : this("", "", User("", "", ""))

Firebase push:



is missing a constructor with no arguments

Is there a better solution for this?

Answer Source

Use default arguments:

class Video(var id: String = "", var url: String = "",
    var owner: User = User("", "", ""))

(also, consider using val).
