FlutterInappPurchase.buyProduct(skuId) errored even though purchase was successful

[mrmikezhang]

Version of flutter_inapp_purchase

flutter_inapp_purchase: ^0.8.5

Platforms you faced the error (IOS or Android or both?)

iOS

Expected behavior

Purchase non-consumable without error using FlutterInappPurchase.buyProduct(skuId)

Actual behavior

The product is successfully purchased, but Apple somehow throw an PlatformException, and ask the user to re-enter their password. Sometimes, the user needs to press the buy button again and Apple will ask the user to restore the purchase because they already own it. I am wondering if I should use FlutterInappPurchase.buyProductWithoutFinishTransaction instead or if that's going to make any difference.

Tested environment (Emulator? Real Device?)

real device

Steps to reproduce the behavior

Happens intermittently

Hope you can shed a light on this, I am read all the docs, couldn't seem to find a solution around it.
Thank you.

@mrmikezhang Yes. This is generally unexpected use-case generated by Apple. I've made a workaround for react-native-iap in PR and not yet for this one. I wish I can get back here to support this in this plugin too.

@hyochan Thanks for getting back to me. It's good to know that I am not causing the problem. Right now I am using buyProductWithoutFinishTransaction to see if that will help mitigate the problem.

@mrmikezhang Hi there. I am trying to manage this problem in this plugin also. See #58.

Closing this for now. Please reopen when this isn't working as expected.
