Code with error

File flutter_inapp_purchase.dart:

The fix is very simple. Just replace the code lines mentioned in the description with:

List<PurchasedItem>? historyNullable = await getPurchaseHistory();
      var history = historyNullable ?? [];

and

List<PurchasedItem>? purchasesNullable = await getAvailablePurchases();
      var purchases = purchasesNullable ?? [];

Thank you for fast update!!!
