stripe: Payment flow never cancel

Platform

Describe the bug When you call Stripe.presentPaymentFlow() it opens a closable modal sheet. Unfortunately, the return of this function is inconsistent as it’s not able to distinguish between the modal sheet being closed or a credit card being selected. Actually if you close it with the cross, you get the cardNumber of the default selected credit card and the PaymentFlowEventsEnum.Completed event is triggered instead of PaymentFlowEventsEnum.Canceled. This is not what’s expected.

To Reproduce Steps to reproduce the behavior:

1. Call Stripe.presentPaymentFlow()
2. Press the cross to close the modal
3. See the PaymentFlowEventsEnum.Completed being triggered and the function return the default selected card.

Expected behavior The PaymentFlowEventsEnum.Canceled being triggered on cancel.

Edit I tested with the iOS Simulator and that doesn’t work either. The default selected payment method is returned.

Here is a screenshot taken right after presentPaymentFlow(). Pressing the cross is equivalent to pressing on Google Pay or on the credit card already registered, depending on the default selected payment method.
