Get error in getting result of purchaseDetail method.

[arefhosseini]

for checking purchase of user I use purchaseDetail(...) as code below:

MainMethod:

Future<Map<String, dynamic>> result = BazaarUtils.purchaseDetail("sample2");
      result
          .then((result) {
            if (result == null) {
              print("Purchase is null");
            }
            else {
              print("Already Purched");
            }
          })
          .catchError((error) => print('Detail error: $error'))
          .whenComplete(() {
            widget.onPushLoadingWidget(false);
          });

BazaarUtils.purchaseDetail:

static Future<Map<String, dynamic>> purchaseDetail(String sku) async {
    Map<String, dynamic> result = await CafebazaarFlutter.getPurchase(sku: sku);
    return result;
}

But in logs I got these error:

Detail error: NoSuchMethodError: The getter 'length' was called on null.
    Receiver: null
    Tried calling: length

I already use initPay(...) for initializing payment.
How can I check that user purchased some product?
Thanks.

you can use this

Map<String,dynamic> result = CafebazaarFlutter.getPurchase(sku:"your product sku")

the result
