Hi,
My name is Yaowen Mei ([email protected]), I am doing an internship at firestore SDK team, and my project is to implement firestore kotlin SDK serialization.

I saw your ticket: firebase/firebase-android-sdk#2916
Thank you very much for your suggestion, and I am just wandering, could you please explain more about your first 2 comments for the limitation section please?

1) Kotlin and Java Bean interfaces do not work too well together. Specifically, Kotlin automatically generates getters and setters. However, if the data class implements an interface, then the "override" keyword apparently generates conflicting getters that breaks POJO serialization.
2) Does not handle generics, or at least it's unclear how to handle generics.

What I have tried:

1. use the current sdk, I created a interface, and concrete class implemented the interface, and I tried to de-serialize the class object from firestore with:

interface Human {
    val name: String?
}

class NewStudent:Human {
        override val name: String?
            get() = "child_name"
}

docRef.get().addOnSuccessListener { documentSnapshot ->
    val student = documentSnapshot.toObject(NewStudent::class.java)
    Log.v("TEST", student!!.name.toString())
}

I didn't have any break issue.

2. I want to duplicate the handle generics limitation issue as well, but I want to double check with you that what you really mean by handle generics?

Thank you very much for your help~
