How do I get the document ID for a Firestore document using kotlin data classes

Question

I have kotlin data class

data class Client(

    val name: String = \"\",
    val email: String = \"\",
    val phone: String =\"\") {
constructor():this(\"         


        

Answer 1

Here is how I solved the problem.

data class Client(
    val name: String = "",
    val email: String = "",
    val phone: String ="",
    @get:Exclude var id: String = "") {
constructor():this("","","")
}

I use @get:Exclude on the id to make sure the id doesn't get sent to Firestore on save, and then when fetching the list of clients do:

snapshot.documents.mapTo(list) {
            var obj = it.toObject(Client::class.java)
            obj.id = it.id
            obj
        }

Setting the id of the new object to the id of the document reference.
