I have implemented in-app purchases in my Flutter app with an auto-renewable subscription priced at 199. Some users have purchased this plan. After that, I changed the price of the plan to 250. I display the price directly from Play Store or App Store’s purchase details. Now, even for users who purchased the plan at the previous price, it is displaying the current price. I want to show the price at which the user purchased the plan.

_productsShow[index].rawPrice.toInt()

this is how i am showing the price .

i tried to search this issue online but not found anything.
