Flutter SDK: how to determine if a user is eligible for a free_trial offer?

After upgrading the SDK to version 3.10, we faced a situation where users who had previously used a free_trial offer are now able to use it again, since the Paywall Product Subscription field always includes a phase with such an offer.

Any way to determine if the user is allowed to use a free trial phase?
