Full example on how to use this plugin

[macmatrix]

Hello

I have just created an article on how to use this amazing plugin using Firebase as a server. Check it out

Thank you @jonasbark and @nicowernli for making the plugin available to use!

Great tutorial, @macmatrix . I was wondering, while handling this part

 PaymentMethod paymentMethod = PaymentMethod();
  paymentMethod = await StripePayment.paymentRequestWithCardForm(
    CardFormPaymentRequest(),
  ).then((PaymentMethod paymentMethod) {
    return paymentMethod;
  }).catchError((e) {
    print('Errore Card: ${e.toString()}');
  });

When do you receive an error? As I can add any number of the credit card - all the time it goes through. Any advice on that?

[macmatrix]

If you put an invalid card number you cannot move ahead. This is built in in the stripe sheet.

Also if you put a valid credit card but your are not able to get a payment method from stripe you are going to have alert pop up.

You can test all scenario with some test credit card made available from Stripe: https://stripe.com/docs/testing

[deimantasa]

Yes, I'm aware about testing specific cards. That's why Im curious. For me, catchError never gets triggered. I always receive paymentMethod object. Just tried with 4000 0000 0000 9987, 12/23, 123.

[macmatrix]

Understood. So then stripe send a PM always and we can remove the catch error routine since we have other checked later on

Hey @macmatrix , have you tried plugging it in to GPay production? As I do have one issue - was wondering if you faced it before - https://github.com/jonasbark/flutter_stripe_payment/issues/127

[macmatrix]

Hi, no I did not try a real production transaction. Which error did you experienced?

[deimantasa]

Full issue here - https://github.com/jonasbark/flutter_stripe_payment/issues/127

I have a feeling, no-one tried to proceed with production Google Pay variation. I'm reaching out GPay and Stripe staff - both are very confused. Stripe is looking into it.

GPay Test env - works fine. Production - doesn't.

[macmatrix]

Ok thanks for exploring this. Stripe has a great support team in freenode. Good to ask there

IRC: Technical Help For Developers If you have technical questions, chat live with our developers in #stripe on freenode.

[macmatrix]

@zeromaro did you manage to find a way to make a real payment?

[deimantasa]

No, Google support seems to be completely off the ground - extremely slow and not really helpful. Got in touch with Stripe - much more helpful, but they don't officially support Flutter for now therefore as well, not much in depth suggestions. Therefore I just scrapped GPay from my app..

[macmatrix]

mmm that's not a good news. Does it work with Apple Pay? and with credit card?

[deimantasa]

Yes, ApplePay works perfectly. Credit Card too - however with credit card, there needs to be done extensive logic in the backend, because as I mentioned earlier - Stripe lib. doesn't detect immediately if CC is valid or not (only the basic identification). So in the backend you'll have to make some calls to understand if CC is correct and it can be charged, otherwise return an error to the user.

ApplePay sheet pops up in iOS Simulator but not on my real iPhone. Any idea?

Instead credit card form shows up in both places.

[macmatrix]

@JoeHsiao is Apple Pay enabled in your real iPhone?

Write this code when you try to make the payment and let me know what do you get

bool deviceSupportNativePay = await StripePayment.deviceSupportsNativePay();
bool isNativeReady = await StripePayment.canMakeNativePayPayments( ['american_express', 'visa', 'maestro', 'master_card']);
print(deviceSupportNativePay); print(isNativeReady);

[JoeHsiao]

@macmatrix

It was my mistake. I hadmerchantId in initState() in a wrong format. It was merchant.merchant.appname, and it should be merchant.appname. After correction, the ApplePay sheet shows up fine on my iPhone!

[macmatrix]

@zeromaro I have tested in production and it works fine with me for both Android and Apple, so you must have some bug somewhere maybe in the google payment set up

[JoeHsiao]

@macmatrix, is it a must to have a standard Stripe account as mentioned in the tutorial? I didn't do any of those because those platform terms are very confusing to me, and I still get a vendor account from Stripe that I can use in the javascript code.

My server is having trouble creating a payment intent, and I am wondering what the cause could be.

[macmatrix]

@JoeHsiao yes you need a standard account first of all because the stripe fee are much lower than a custom account and then because it simplify a lot your work: with a standard account you need to do basically nothing for the user onboarding. Lastly if you use a standard account you are not responsible for the transaction so you are limiting your responsabilies a lot

[JoeHsiao]

This is more a Stripe question, and the more I read the more I am lost. So what you suggest is I will use my existing Stripe account as a "marketplace", and I will create another Stripe account as "seller" in the marketplace, and set up the seller account in Connect, and in my app I will charge to the "seller" account?

[macmatrix]

@JoeHsiao if you want to sell services then you do not need a marketplace. you can simply create a stripe account and use it straight away. a marketplace is something like eBay. You Would act as eBay (the platform) and there would be different sellers selling their products and you would get a commission for every sales
