facing issue with in-app purchase of consumable products in android, flutter

Question

The payment flow is working completely fine, but when the slow test card is used the consumable product cannot be purchased again. the plugin used is in_app_purchase: ^3.0.4. To reproduce the issue:

1. purchase the product with "slow test card, Approves after a few minutes" option.
2. once initiated then close the application.
3. open the application. The purchase stream will be triggered and await InAppPurchase.instance.completePurchase(purchaseDetails); will successfully run for that purchase. But after that, when I try to purchase the product, the google play in-app-purchases handler throws an error: You already own this item. The whole process works successfully when app is not closed in the process.

and also i'm not able to convert that product back to consumable.

code snippet

purchaseParam=PurchaseParam(productDetails:selectedProduct);
InAppPurchase.instance.buyConsumable(purchaseParam: purchaseParam);

_subscription = purchaseUpdated.listen((purchaseDetailsList) {
      log("initiating purchase stream");
      p_purchaseList = purchaseDetailsList;
      listenToPurchaseUpdated(purchaseDetailsList);
    }, onDone: () {
      log("done..");
      _subscription.cancel();
    }, onError: (error) {
      log("error in payment is = $error");
    }, 
);

void listenToPurchaseUpdated(List<PurchaseDetails> purchaseDetailsList) async {
  log("listening to purchases 1 ");
  purchaseDetailsList.forEach((PurchaseDetails purchaseDetails) async {
    if (purchaseDetails.status == PurchaseStatus.pending) {
    } else {
      if (purchaseDetails.status == PurchaseStatus.error||purchaseDetails.status == PurchaseStatus.canceled) {
        print("error :${purchaseDetails.error!}");
      }
      else if (purchaseDetails.status == PurchaseStatus.purchased || purchaseDetails.status == PurchaseStatus.restored) {
        FirebaseDataStorage().uploadPurchaseInfo(purchaseDetails); // performing tasks once product is purchased
      }
      if (purchaseDetails.pendingCompletePurchase) {
        log("listening to purchases 5 ");
        await InAppPurchase.instance.completePurchase(purchaseDetails);
      }
    }
  });
}

the stream is listened in initstate
