我有一个产品的数组列表，当我使用更新方法将其设置为firestore文档时，尽管我模型中的变量名称为CapWords，变量的命名仍变为驼峰式。这样您就可以在第一个屏幕截图中看到产品的元素是CapWords，但是当我对其进行更新时，它无缘无故变成了驼峰式保护套

override fun onProductClicked(sku: FirebaseProduct) {
skuItems[0].StatusId = 123 //try to update element in array of products
FirestoreHelper.update(skuItems)}

fun update(skuItems: ArrayList<FirebaseProduct>) {
db.collection(Constants.PURCHASE_RECEIPTS).document(1.toString())
.update("Products",skuItems)} //when i updated the array all the object names turned into camle-case

这是产品购买收据的模型类别

class FirebasePR {

constructor()
constructor(
    maxabPurchaseReceiptId: Long,StatusId: Long?,PoId: Long?,ScannedAt: String?,EndedAt: String?,maxabWarehouseId: Long?,maxabDeliveryDate: String?,ReceiverId: Long?,AreaId: Long?,AdminId: Long?,Products: List<FirebaseProduct>?,NumOfRemaining: Long?,NumOfReceived: Long?

    this.MaxabPurchaseReceiptId = maxabPurchaseReceiptId
    this.StatusId = StatusId
    this.PoId = PoId
