I know this library flutter_stripe, which to me seems to be very limited in stripe interactions, it only does paymentIntent creation and that is basically it. Please do argue if I am wrong.
I am looking forward to see if there are other packages, if any, for flutter to interact with stripe in more depth, I am trying to avoid Android/IOS native languages.
I do these in backend: create stripe customer, create setup intent for each customer as they try or either add bank card or make purchase.
I am looking forward that client will interact to stripe for the following:
1 Confirm setup intents
2 Send card data to stripe
Another question, could you please assess my payment flow? If it is faulty please recommend another way
Once setupintent is confirmed for the user, they hit backend for whatever purchase they want to make, backend contacts Stripe, fetches the setupintent, creates and confirms the paymentintent.
Thank you, I appreciate help.
