Stripe Payment not working in test mode for Ireland, USA and more.

[Ritikrai09]

We are trying to integrate the payment gateway we have done following things :

1. We integrate flutter_stripe: 11.5.0 in flutter.

2. The card number we have tried are:

   • 4242 4242 4242 4242, any future expiry and 123, country USA and postal code 10001
     ( NOT working )
   • 4000 0035 6000 0123, any future expiry and 123, country ireland. ( NOT working )
   • 4000 0035 6000 0123, any future expiry and 123, country india. ( working )

3. We are able to open the page but it is returning "something went wrong".

Please help me understand why it's not working as expected. Test cards also failed to work.
We have gone through stripe docs and it's documentation given in flutter package but not able to figure it out.
