Hey @Panudech Changthong, just to make sure here: are the products that you have set up in your configuration file, also set up in the RevenueCat dashboard? 

The steps to do that are detailed here: https://docs.revenuecat.com/docs/entitlements#revenuecat-configuration

The products that you have in the storekit configuration file need to be set up in the RevenueCat dashboard, and the product identifiers need to match exactly so that they show up in offerings. In addition, you’ll have to set up packages and offerings (also described in the link above)

@Panudech Changthong could you share the debug logs? They might shed some light on what’s going on here

@Panudech Changthong I think that might be because the line hasn’t executed yet? The object should be non-null when you move to the `print` line. 

 

Here’s how to get debug logs https://docs.revenuecat.com/docs/debugging. Could you attach them here?

@Andy

My debug log don’t show message i don’t understand why

According document just code below 

 

await Purchases.setDebugLogsEnabled(true);
await Purchases.setup(key,    appUserId: "my_app_user_id");

 

On my schema i unchecked OS_ACTIVITY_MODE

** Right now i dowgrade lib from 4.1.0 to 3.10.0

 

uncheck OS_ACTIVITY_MODE
Code basic debugging

I’m not sure why you’re not seeing the debug logs, perhaps they don’t show up in that specific IDE? Have you tried seeing what is displayed when running from Xcode?

@Panudech Changthong you should try running the iOS app directly from Xcode, I believe that’s the only way to get the logs from a Flutter app on iOS. 

 

Are you also having issues with the Android setup? Or does that one work as expected?

@Andy 

I found the problem same again when i use lib on version 4.0.0 

below it errror message can’t fetch offerring

flutter: information CustomerInfo(entitlements: EntitlementInfos(all: {}, active: {}), allPurchaseDates: {}, activeSubscriptions: [], allPurchasedProductIdentifiers: [], nonSubscriptionTransactions: [], firstSeen: 2022-08-11T08:41:16Z, originalAppUserId: appd40d1e398d, allExpirationDates: {}, requestDate: 2022-08-11T08:55:41Z, latestExpirationDate: null, originalPurchaseDate: null, originalApplicationVersion: null, managementURL: null)

More information: https://rev.cat/why-are-offerings-empty, readable_error_code: CONFIGURATION_ERROR, readableErrorCode: CONFIGURATION_ERROR, underlyingErrorMessage: }, null)

 

in the other hand if i use lib version tomorrow is 3.10.0 not problem becasue Identifying below code

await Purchases.setup("public_sdk_key", appUserId: "my_app_user_id");

 

but on version 4.0.0 

PurchasesConfiguration data = await PurchasesConfiguration(key);

 

Why can’t set appUserId 

then i try this 

PurchasesConfiguration data = await PurchasesConfiguration(key);data.appUserID = "THIS IS MY KEY";

 

you know solution on 4.0.0 upper i don’t know how to config on the document still use format older version

set Identifying old version

 

change log on https://pub.dev/packages/purchases_flutter/changelog

 

on Changelog tell change Purchase.setup tp Puchase.configure

 

Tell/suggest me to use on 4.0.0 version I find solution not found.

@Panudech Changthong the old configuration method is deprecated but not removed yet, so it should still work. Are you getting an error message when using it? 

Thanks for letting us know about the outdated docs, we’ll get them updated ASAP. 

In the meantime, here’s an example of how the new configuration code should look: 

```

PurchasesConfiguration configuration = PurchasesConfiguration("your key here")
    ..appUserID = "your appUserID here";
}
await Purchases.configure(configuration);

```

 

You can see this being used in our sample app here:

https://github.com/RevenueCat/purchases-flutter/blob/feca797cadfd3e1abdb74f0801e5e80b61161052/revenuecat_examples/MagicWeather/lib/src/views/home.dart#L40
