Lib not giving base plan info for the new google play subscription structure

[marianolc]

Base on how subscriptions works now:

https://support.google.com/googleplay/android-developer/answer/12124625?sjid=10922029906795459446-EU

Where everything should be in the same subscription:

For example, a doing a iap.getPurchaseData(result) from a validation I get the following information:

[
   {
      "service":"google",
      "status":0,
      "packageName":"app.yyyy",
      "productId":"yyyy",
      "purchaseToken":"xxxx",
      "startTimeMillis":1709565742304,
      "expiryTimeMillis":1709568021739,
      "autoRenewing":false,
      "priceCurrencyCode":"USD",
      "priceAmountMicros":10770000,
      "countryCode":"XX",
      "developerPayload":null,
      "cancelReason":1,
      "orderId":"GPA.0000-0000-0000-00000..6",
      "purchaseType":0,
      "acknowledgementState":1,
      "kind":"androidpublisher#subscriptionPurchase",
      "transactionId":"xxxx",
      "quantity":1,
      "expirationDate":"1709568021739",
      "cancellationDate":"1709568021739"
   }
]

If I call the subscriptionV2 api from google:

https://androidpublisher.googleapis.com/androidpublisher/v3/applications/${packageName}/purchases/subscriptionsv2/tokens/${purchaseToken}

In the response there is an array of "LineItems" that I guess is what is mapped to get the previous object. In the line items the basePlanId is there:

{
   "kind":"androidpublisher#subscriptionPurchaseV2",
   "startTime":"2024-03-04T15:22:22.696Z",
   "regionCode":"XX",
   "subscriptionState":"SUBSCRIPTION_STATE_EXPIRED",
   "latestOrderId":"GPA.0000-0000-0000-00000..6",
   "canceledStateContext":{
      "systemInitiatedCancellation":{
         
      }
   },
   "testPurchase":{
      
   },
   "acknowledgementState":"ACKNOWLEDGEMENT_STATE_ACKNOWLEDGED",
   "lineItems":[
      {
         "productId":"yyyy",
         "expiryTime":"2024-03-04T16:00:21.739Z",
         "autoRenewingPlan":{
            
         },
         "offerDetails":{
            "basePlanId":"BASE_PLAN_ID",
            "offerId":"starter",
            "offerTags":[
               "monthly",
               "starter",
               "starter-test"
            ]
         }
      }
   ]
}

This value is important because is the only way to recognize "gold" / "silver" plan for example.

Any update on this, @voltrue2 ? This is critical for updating the subscription based on Google's latest recommendations.
