When trying with Invalid card details in Live throwing 'Null' is not a subtype of type 'Map<String, dynamic>' in type cast

[SoorajSoman]

First of all thanks for this great library. I'm trying stripe payment with Invalid card details (valid card number and invalid expiry or ccv combination ) in Live mode throwing exception 'Null' is not a subtype of type 'Map<String, dynamic>' in type cast while Stripe.instance.confirmPaymentMethod is called.I checked the other issues reported with same exception but it is of different context hence raising as a new one.

I'm following https://github.com/flutter-stripe/flutter_stripe/blob/main/example/lib/screens/webhook_payment_screen.dart implementation

To Reproduce
Steps to reproduce the behavior:

1. Entering number test card 4242 into the cardfield in live
2. Tapping the confirm button.
3. Observe a failure with exception (including the part of the stack trace, belonging to this package)
   'Null' is not a subtype of type 'Map<String, dynamic>' in type cast while Stripe.instance.confirmPaymentMethod is called.

Expected behavior
Any response from library to handle invalid card details

Additional context
Could any one please confirm whether this is achievable with current version of library and implementation I'm following?

@SoorajSoman I need a bit more information about it which version of the library do you use? Also can you provide me the full stack trace?

@SoorajSoman in version 1.2.0 we made significant improvements related to the response objects . I would ask you to try it out on this version and let me know if the issue exist.

[SoorajSoman]

@remonh87 It was not 1.1.2 rather 1.2.0 I tried and had the issue with the keyboard in some Android devices (marshmallow and pie OS ), the main blocker CardFields were taking input from keyboard or even not focussing ,So thats the reason switching back to 1.0.2 in which happy path was working as expected but got the above issue. if needed I can try with 1.2.0 again and update over here.

@SoorajSoman there were some issues in the previous libraries with result objects which we fixed form version 1.2.0 would be great if you can verify if the issue still occurs
