I just improved the solution of @iCediCe, and add methods to DocumentSnapshot and QuerySnapshot.

interface HasId {
    var id : String
}

inline fun  DocumentSnapshot.toObjectWithId(): T {
    return this.toObject(T::class.java)!!.also {
        it.id = this.id
    }
}

inline fun  QuerySnapshot.toObjectsWithId(): List {
    return this.documents.map {
        it.toObjectWithId()
    }
}

And usage:

data class User(
    @get:Exclude
    override var id: String,
    ...
): HasId


val user = documentSnapshot.toObjectWithId()
val users = querySnapshot.toObjectsWithId()
