Migrating to 6.0 - freeTrialPeriod and subscriptionPeriod not found

Hello,

I’m struggling with the RevenueCat update from 5.x to 6.4.0 on Android.

I have currently a method to load the weekly subscription, however product doesn’t have subscriptionPeriod any longer.
 

fun loadWeeklyProduct(onPackageLoaded: (Package?) -> Unit) {
    Purchases.sharedInstance.getOfferingsWith(
        { error ->
            // An error occurred
        }) { offerings ->
        val annualProduct = offerings.current?.availablePackages?.firstOrNull { item ->
            item.product.subscriptionPeriod == "P1W"
        }
        onPackageLoaded(annualProduct)
    }
}

And with this other method I would check if they still are eligible for Trial. Sadly product also no longer has any freeTrialPeriod.

private fun fillTrialOrNormal(it: Package) {
    val hasFreeTrial = !it.product.freeTrialPeriod.isNullOrEmpty()
    Utilities().checkTrialUsedUp(it.product.sku, hasFreeTrial) { trialUsedUp ->
        var title = ""
        var header = ""
        if (trialUsedUp) {
            title = "${it.product.price} / Year"
            header = getString(R.string.upgrade_to_premium)
            binding.premiumTextId.text = header
        } else {
            title = "Start Your 3 Days Free Trial,\nThen ${it.product.price} / Year"
        }
        binding.trialPurchaseButtonId.text = title
        binding.trialPurchaseButtonId.isEnabled = true
    }
}

I couldn’t find anything about this on the migration document.  I would really appreciate any hints how to achieve this.  

Many Thanks,

Houman
