Instantiating `CustomerSession` restart the `initCustomerSession` process instead of just referencing the initialised one

[vinnytwice]

I'm using flutter_bloc for state management and initialise CustomerSession in PaymentScreen's initState() as:

class _PaymentScreenState extends State<PaymentScreen> {
  Image logo;
  @override
  void initState() {
    super.initState();
    logo = Image.asset('assets/notification.png');
    isVerified = widget.user.phoneVerified;
    try {
      PaymentMongoRepository _mongoRepository = PaymentMongoRepository();
      Stripe.init(
        Environment.stripePublishableKey,
        stripeAccount: widget.user.stripeId, // CustomerId ( buyer ), not AccountId ( seller)
        // returnUrlForSca: "stripesdk://3ds.stripesdk.io", // not existing parameter???
      );
      Future<String> createCustomerEphemeralKey(
          {String apiVersion, String customerId}) async {
        String ephemeralKey;
        await _mongoRepository
            .getEphemeralKey(
                apiVersion: apiVersion, stripeId: widget.user.stripeId)
            .then((key) {
          ephemeralKey = key;
          print(
              '∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞  PaymentScreen createCustomerEphemeralKey key is: $key');
        }).catchError((e) {
          print(
              '∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞  PaymentScreen createCustomerEphemeralKey key error: $e');
        });
        return ephemeralKey;
      }

      /// EphemeralKey needs to be in a json encoded form or you get:
      /// Unhandled Exception: Failed to parse Ephemeral Key, Please return the response as it is as you received from stripe server

      CustomerSession.initCustomerSession(
          (apiVersion) => createCustomerEphemeralKey(
              apiVersion: '2020-08-27', customerId: widget.user.stripeId),
          stripeAccount: widget.user.stripeId);
    } catch (error) {
      print('Stripe error: $error');
    }
  }
 ...

then initialise PaymentBloc which instantiate PaymentStripeRepository in which I do all the customer related operations using CustomerSession.

The problem is that when I call an operation like retrieveCustomerPaymentMethods ( the first one I do ) I get the error The provided key 'ek_test_YW*********************************************************************_******2Cdw' does not have access to account 'cus_Ku8ajLiFEsdnEB' (or that account does not exist). Application access may have been revoked. I checked and in my Stripe dashboard I have test mode enabled and the customer shows up so that's ok. The problem I found is that when I instantiate CustomerSession as below in the PaymentStripeRepository I see that my server generates another EphemeralKey and use that to carry on any operation as prints below show: flutter app:

node server prints:

}

Now this shows that calling CustomerSession.instance calls again the createCustomerEphemeralKey from CustomerSession.initCustomerSession in PaymentScreen's initState as the print I setup there only show up twice.

Why is instantiating CustomerSession restart the initCustomerSession process instead of just referencing the initialised one?? Many thanks

This is the repo:

class PaymentStripeRepository {
  Stripe stripe = Stripe.instance;
  CustomerSession customerSession = CustomerSession.instance;

  Future<List<Map<String, dynamic>>> retrieveCustomerPaymentMethods(
      {String customerId}) async {
    print('PaymentStripeRepository retrieveCustomerPaymentMethod started');
    List<Map<String, dynamic>> paymentMethods;
    await customerSession.listPaymentMethods(type: 'card').then((value) {
      if (value != null) {
        paymentMethods = jsonDecode(value['data']);
        print(
            'PaymentStripeRepository retrieveCustomerPaymentMethods list is :$paymentMethods');
      }
    }).catchError((e) {
      print('PaymentStripeRepository retrieveCustomerPaymentMethods error: $e');
      throw e;
    });
    return paymentMethods;
  }
}

Are you still having issues here? If so, I'll follow up

[vinnytwice]

@ezet yes, I still have this issue, is there anything O should look-up?

[preteambuy]

@vinnytwice can you help me out with how to tokenize the card?
