Приложение iOS завершается при использовании in_app_purchase в 18.3.1 в Flutter ⇐ IOS

[Anonymous]

Я изучаю трепетание и реализовал in_app_purchase для Android и iOS, однако он отлично работает в обеих платформах, но имея приведенный ниже выпуск в iOS 18.3.1. Версия, которую я имею < /p>
in_app_purchase: ^3.1.13
< /code>
Я сталкиваюсь с этой проблемой < /p>
flutter: Purchase successful!
flutter: Purchase finally :
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull length]: unrecognized selector sent to instance 0x20c8db910'
