Closed Muhammed-Irfan closed 1 week ago

Muhammed-Irfan commented 1 month ago

Steps to reproduce

  1. Request a purchase by buying a non-consumable product.
  2. Enter necessary credentials if needed (e.g., email, password).
  3. Click on Sign In.

This is working fine in Android.

Expected results

The purchaseStream should fire after a successful purchase on iOS.

Actual results

The purchaseStream is not fired after a successful purchase on iOS and the bottom sheet to purchase keeps popping up again.

@Muhammed-Irfan Can you provide us only minimal but complete runnable reproducible code sample without any third party package implementation, that still shows the reported behavior ?

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now. If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones. Thanks for your contribution.
