This also happens on IOS.

I created a pull request to fix this issue. Hopefully it will get merged soon ;)
In the meantime you can use my fork like this. Hope it helps ;)

In your pubspec.yaml

  flutter_stripe:
    git:
      url: https://github.com/Flucadetena/flutter_stripe.git
      path: packages/stripe

dependency_overrides:
  stripe_platform_interface:
    git:
      url: https://github.com/Flucadetena/flutter_stripe.git
      path: packages/stripe_platform_interface

I have somehow the same problem. Collecting payment through cardForm.

1. Create Intent
2. CreatePaymentMethod
3. ConfirmPayment. --> using client_secret and methed_id

If the card is 3d secured the user is redirected to hooks.stripe.com to authenticate the card, but on closing that page it throws StripeException with FailureCode.failed rather than FailureCode.cancelled. since the user explicitly closed the payment process. I am expecting to get FailureCode.cancelled.

@Flucadetena @jamesblasco @ovchars2 @cornwe19 .

Can someone please help me out this?

Hi @phawadshah I'm sorry but I'm still using my fork to avoid this issue, I can not tell you more than to use it or check out what I did and see if it helps :)

@Flucadetena I did use your fork but it did not work. I think you misread my issue.

1. Closing paymentSheet
   It throws the expected exception of cancelled.

2. My issue is when Confirming a payment via card, and Payment intent status is "requires_action" and you close/cancel the process. You can look this in the photo attached.

I am expecting failureCode.cancelled and it throws failed, since it was cancelled by the user.
