com.revenuecat.purchases.common.PurchasesPeriod.parse (PurchasesPeriod.java:125)

App crash on iOS when calling makePurchase() with non-existing product ID

I noticed that if I call makePurchase(productID) on iOS with a product ID that does not exist in App Store Connect (but that does exist in Google Play Store), the entire app crashes. Usually there is no error message, only a

Lost connection to device.

A few times I've seen this kind of output as well

Failed to send request: {"jsonrpc":"2.0","id":"41","method":"resume","params":{"isolateId":"isolates/707523504"}}
Lost connection to device.

I'm not sure what's going on, but a guess is that something is crashing in the native iOS code? Not sure why it causes the entire app to crash instead of generating a PlatformException though.

This has only happened on iOS, and I'm testing it on an iPad Mini with iOS 12.4. This is the output from flutter doctor:

Doctor summary (to see all details, run flutter doctor -v):

Expose `userDefaults` in `Purchases.configure` just like iOS repo

Problem

The original problem that requires this change, is that RevenueCat uses NSUserDefaults as a data layer. The actual problem is using the default instance and not a separate standalone instance specially instantiated for RevenueCat.

This means when NSUserDefaults is reset/reloaded/cleared, then RevenueCat will lose track of all persisted data.

This might happen automatically for some reason, abnormalities with NSUserDefaults shared instance that puts RevenueCat in an undefined state.

Fix

With this introduction for the problem, the solution is simply taking in an optional string ID as a parameter within Purchases.Configure that would create the standalone NSUserDefaults instance automatically for us. Like this solution in an issue from iOS repo. Or at least just make it so that RevenueCat uses a hardcoded NSUserDefaults domain ID.

FatalException *** -[__NSCFConstantString stringByAppendingString:]: nil argument -[NSPlaceholderString initWithCharactersNoCopy:length:freeWhenDone:]

Hi,

I have an app with about 800 users and the library works for 99% of people, but I saw this in Crashlytics today.

Any thoughts? I can provide more info if needed.

Object.noSuchMethod getOfferings

Hey,

if there are no offerings available the current parsing of getOfferings will throw an exception.
We found also that this can happen in production, why we are not sure, possible network issue? If a network error could lead to this as well then this is a second issue because I expect that the native plugin throws a PlatformException with NetworkError code.

Non-fatal Exception: dart:core-patch/object_patch.dart 53 in Object.noSuchMethod
0  ???                            0x0 Object.noSuchMethod + 53 (object_patch.dart:53)

2  ???                            0x0 new Offerings.fromJson + 13 (offerings_wrapper.dart:13)
3  ???                            0x0 Purchases.getOfferings + 108 (purchases_flutter.dart:108)

We use version: 1.0.1 of the plugin and Flutter (Channel beta, v1.12.13+hotfix.6)

AdvertisingIdentifier

We have created an app that is in the App store 'made for kids' special category.
The app was rejected due to IDFA being present. Having searched our app it appears this comes from the Revenue Cat plugin.
fgrep -R advertisingIdentifier .
There are entries in RCAttributionFetcher.h, RCPurchases.m, and RCAttributionFetcher.m

Is it possible to remove this from the plugin so that we can successfully submit our app? Love the plugin and the RevenueCat approach, so really wouldn't want to remove our revenuecat integration and use another approach for subscriptions.

If there is a hack to do so please advise, any solution accepted right now!

Thanks,
Tom

Android crash

Hi,

I have migrated IAP to RevenueCat in my app. iOS works fine, but Android works only on 1st launch after deleting the app from test device. Looks like there's some bogus data in SharedPreferences. Any suggestions what I could try?

Empty Offers Query

I'm having an issue with blank Offers coming back from the SDK. I'm on the flutter dev channel working in iOS:

Flutter 1.16.1 • channel dev • https://github.com/flutter/flutter.git
Framework • revision e6b0f5f238 (9 days ago) • 2020-03-18 21:56:02 -0400
Engine • revision 216c420a2c
Tools • Dart 2.8.0 (build 2.8.0-dev.15.0 96cf889e6b)

I noticed that the Pod for Purchases is at 3.2.1 and the flutter app is using the 3.0.x releases.

Expose `originalPurchaseDate` from `purchases-ios`

In reference to this purchases-ios PR, could originalPurchaseDate be exposed for flutter users please?

The currently exposed property originalApplicationVersion actually corresponds to the build number and not the version name. This is bad for migrating users since not all build numbers are unique for all versions. See the discussion in the PR linked above. All new developers of the project have to know this important optional constraint that is having distinct incremental build number regardless of version name.

This is impactful and wouldn't take much time to implement so I hope this gets you attention please.

getOffering returns null

Hi,

When I print out all the offerings I have, you can see the offerings particularly the one identified by the string "Default".

Offerings{current: Offering{identifier: Default, serverDescription: Subscription options., availablePackages: [Package{identifier: $rc_monthly, packageType: PackageType.monthly, product: Product{identifier: com.phntm.carbon.subscription, description: The subscription is required to access Carbon, title: Full Access, price: 11.989999771118164, priceString: $11.99, currencyCode: USD, introductoryPrice: null}, offeringIdentifier: Default}], lifetime: null, annual: null, sixMonth: null, threeMonth: null, twoMonth: null, monthly: Package{identifier: $rc_monthly, packageType: PackageType.monthly, product: Product{identifier: com.phntm.carbon.subscription, description: The subscription is required to access Carbon, title: Full Access, price: 11.989999771118164, priceString: $11.99, currencyCode: USD, introductoryPrice: null}, offeringIdentifier: Default}, weekly: null}, all: {Default: Offering{identifier: Default, serverDescription: Subscription options., availablePackages: [Package{identifie<…>

However, when I call the getOffering method on this, print(offerings.getOffering("Default"));

it prints out null and because of this when I try to get the Offering's package like this,
Package package = offerings.getOffering("Default").availablePackages[0];

it does not work, error Unhandled Exception: NoSuchMethodError: The getter 'availablePackages' was called on null.

Error when adding purchases-flutter as dependency

Hi Revenuecat team, first of all thankyou for creating this package. I'm able to run this packages in Flutter, but not without problem initially.

When i'm creating a new Flutter project, add purchases-flutter as dependencies and try to run it, i got this error:

e: C:\flutter\.pub-cache\hosted\pub.dartlang.org\purchases_flutter-1.0.0\android\src\main\java\com\revenuecat\purchases\common\common.kt: (101, 37): Type mismatch: inferred type is String? but String was expected

BUILD FAILED in 23s

Steps:

flutter create project_name
Add purchased_flutter: 1.0.0 to pubspec.yaml
Run the project

After checking the example project and some trial and error, i found out that i need to change these files:

<project folder>/android/build.gradle: Change ext.kotlin_version to 1.3.60. Change gradle version to 3.5.2
<project folder/android/gradle/wrapper/gradle-wrapper.properties: Change distribution url to https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

My environments are as follow:

Flutter 1.9.1+hotfix.6
Dart 2.5.0
Windows 10

So i just want to ask what's the minimum requirement to use purchases-flutter? As the documentation doesn't mention it yet.

Create unified error enums or types

https://stackoverflow.com/questions/58410482/exposing-all-revenuecat-purchaseserrorcode-codes-in-flutter?sem=2

Expose error codes as enums or equivalent in Dart so they don't have to be hard-coded.

The proposed solution would be to add something like this

enum PurchasesErrorCode {
  UnknownError,
  PurchaseCancelledError,
  StoreProblemError,
  PurchaseNotAllowedError,
  PurchaseInvalidError,
  ProductNotAvailableForPurchaseError,
  ProductAlreadyPurchasedError,
  ReceiptAlreadyInUseError,
  InvalidReceiptError,
  MissingReceiptFileError,
  NetworkError,
  InvalidCredentialsError,
  UnexpectedBackendResponseError,
  ReceiptInUseByOtherSubscriberError,
  InvalidAppUserIdError,
  OperationAlreadyInProgressError,
  UnknownBackendError,
  InsufficientPermissionsError
}

try {
} on PlatformException catch (e) {
  PurchasesErrorCode errorCode = PurchasesErrorCode.values[int.parse(e.code)];
  switch (errorCode) {
    case PurchasesErrorCode.UnknownError:
    case PurchasesErrorCode.PurchaseCancelledError:
    case PurchasesErrorCode.StoreProblemError:
    // Add rest of cases
  }
}

Package support

Is the package going to be actively supported and evolving? I see that SDK for android and iOS get regularly updated, although there are no commits to flutter SDK for more than a month...

iOS Unable to made a purchase on cancelled subscription still in the sandbox

During integration after move from the in_app_purchases plugin getting error on trying to made reactivation of the subscription previously cancelled in the sandbox during tests with previous plugin

Please advise

I tested to purchase a lifetime entitlement, refunded and revoked it after, waited for the 5 minutes cache for the purchases SDK to be updated, then tried to call the restore purchases function, and still, I can restore or the entitlement is still active.

Pass subscription period to Flutter

It's often useful to get the subscription period to display it or calculate various things before displaying it.

Currently, I am trying to setup RevenueCat on iOS and I have added

AppBundle ID, TunesConnect App-Specific Shared Secret, Didn't add p8 key as it's for iOS offers.

Also added Apple Server Notification URL to AppStore connect

But I am getting an empty offerings list in iOS.

How to unsubscribe ?

Hello, it's possible to use revenuecat futter sdk to call unsubscribe fonction to the store ? I don't see this function. New android rules force the develloper to be clear about informations, and show easy solution for the user to cancel subsription. thank you

iOS app crash on latest Flutter channel

On flutter beta and dev channel, using 1.0.4 version of purchases-flutter, when call method Purchases.getPurchaserInfo() iOS app crashes.

On Android it works.

This is the logs with flutter run:

 └─Compiling, linking and signing...                        12,6s

Actually no logs so I thought it was an issue with the Swift native code. If I run it from Xcode, it works.

Handle Slow card purchases

I'm using a "Slow card" option to test a purchase. Is there a way to get a purchase status when it finishes (in order to show success/error message or direct user to unlocked page, etc)?

I do receive a callback in PurchaserInfoUpdateListener after transaction finished, but I'm not able to say if purchase succeeded or not.

iOS Sandbox Subscription Renewal

This is a duplicate issue of #50 but no one responded.

Flutter 1.17.3 stable
Dart 2.8.4
purchases_flutter 1.1.1

Plan: build

When purchasing a subscription via sandbox, it'll renew 5 times and then auto cancel.

At this point, I'd like to renew the subscription and it fails here. I've tried using both purchase methods purchasePackage and purchaseProduct with no success.

I'd also like to mention that if I close the app and reopen it and try to renew every so often it'll work, but 90% of the time it won't.

Support for stripe subscriptions

For real world goods and services it's possible to use stripe subscriptions instead of apple's IAP subscriptions. Given that Stripe subscriptions are in beta on RevenueCat it would be great if this package would support fetching/purchasing using Stripe in place of the native platform subscription

Custom types missing documentation

Add Support for Android proration rate

For us, it's important to explicitly set the proration rate with Google Play.

There is currently no option in Flutter.

Offline Support for Entitlements

Our app can be used offline and user has a certain quota on how many records he can create.

So we need a way to fetch Entitlement info offline as well (the one fetched recently) so that we can tally user's quota with what entitlement is available to them.

Is there any way to do this already?

Purchases.getEntitlements() results in PlatformException: Text cannot be parsed to a Period

Since upgrading to 0.3.0, when I call Purchases.getEntitlements() I get this PlatformException:

Errors running Pod Install

Every time I add this package to a Flutter project and then try to run it, I get a Pod error. I've tried going back to a completely new Flutter app and running it and it still errors.

Here is the error message:

MacOS Support

I thought MacOS was supported? Can you show me documentation to get started? Works great on iOS and Android. Also is web support for Flutter web added?

How to set auto-renewable subscription?

Perhaps. this question is so dumb, but I really want to know how can I use auto-renewable subscription, I saw your article in the site about restoring, but I couldn't understand how to implement it.

TestFlight users resubscribe every restart

For some reason if you use the subscription action in an app installed through TestFlight it resets the test subscription every time you force close the app. Subscriptions work though the App Store though.

[Android] The product is not available for purchase

No products show up when running on android, no issues with iOS. Looks like Purchases.getProducts(_kProductIds) is returning an empty list.

IOS 13.4 Update After - Flutter

Hello Dear.

Payment does not start after updating.
Sometimes it starts but not as a sandbox user. process is canceled when i enter my password
The mistake I usually get is this PurchasesErrorCode.storeProblemError.
All of this happened after upgrading to 13.4.

Slow test card: RangeError (index): Invalid value: Not in range 0..18, inclusive: 20

Hi, I'm testing purchases with "Slow test card" on Android and right after payment window is closed the Exception is thrown "RangeError (index): Invalid value: Not in range 0..18, inclusive: 20"

Code:

try {
    final purchaserInfo = await Purchases.purchasePackage(package);
} on PlatformException catch (e) {
    var errorCode = PurchasesErrorHelper.getErrorCode(e); //<--- error here
    if (errorCode != PurchasesErrorCode.purchaseCancelledError) {
        print(e);
    }
}

It seems that code for the "The payment is pending." exception is 20.

After data change getPurchaserInfo returns cached data first and only then downloads update

If some purchaser data changes in background (f.e. subscription expires) and the app is trying to get purchaser info
final purchaserInfo = await Purchases.getPurchaserInfo();
purchaserInfo still contains old data.

I can see from the logs that change was detected:
D/[Purchases] - DEBUG(29537): Vending purchaserInfo from cache
D/[Purchases] - DEBUG(29537): Cache is stale, updating caches
D/[Purchases] - DEBUG(29537): Purchaser info updated, sending to listener

But description of the method implies that it should return newest state (at least this is how I understand it):

Gets current purchaser info, which will normally be cached.

Wouldn't it be better if getPurchaserInfo awaited for new data whenever there was a change and returned from cache when there wasn't?

PurchaserInfo missing properties

The documentation mentions that the PurchaserInfo has two properties called Request Date and Original Application Version, but they don't seem to be present in the Flutter version of PurchaserInfo?

The documentation even specifically says that you should user Request Date rather than device time to make time comparisons.

Any plans to support ios subscription offers in the flutter sdk?

I read through the docs here: https://www.revenuecat.com/blog/signing-ios-subscription-offers but couldn't find the necessary calls in the flutter sdk.

Do you guys have plans to implement this?

Report Issue section of docs on pub.dev points to wrong repository

On https://pub.dev/packages/purchases_flutter/#-readme-tab- under the Reporting Issues section, the link is pointing to the purchases-ios repository instead of purchases-flutter.

Expose method to check if purchases are available

https://docs.revenuecat.com/docs/making-purchases#checking-if-purchases-are-available

This one is currently not supported in Flutter, right? I guess it should be easy to expose it via channels since there are examples for both Swift and Kotlin. Do you have it in backlog or maybe there is something that I'm missing?

No way to access Package description?

A description can be set for a Package in the RevenueCat dashboard, but I can't find any way to access it using version 1.1.0 of the Flutter plugin?

Failed to compile on android

Hi Revenuecat team, first of all thank you this package. I'm able to run this packages in Flutter.

I was using the package revenuecat, and now I decided to start using the official library, but I'm having troubles to execute my app when I add to my dependencies

purchases_flutter: ^1.0.4

I'm giving the following error:

`

  }


  @override
  void initState() {
    super.initState();
    id();
    initPlatformState();

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    await Purchases.setDebugLogsEnabled(true);

    Offerings offerings = await Purchases.getOfferings();
    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
