[Exception] when closing customer sheet (Customer Sheet Result deserialization)

[angelorodem]

Describe the bug When getting error from stripe, StripeError.fromJson( returns an error type 'String' is not a subtype of type 'Map<String, dynamic>' in type cast

the code i use is this

Future<void> confirmCustomerSheet() async {
    try {
      // 3. display the customer sheet.
      final result = await Stripe.instance.presentCustomerSheet();
[...]

in this code

_$CustomerSheetResultImpl _$$CustomerSheetResultImplFromJson(
        Map<String, dynamic> json) =>
    _$CustomerSheetResultImpl(
      paymentOption: json['paymentOption'] == null
          ? null
          : PaymentSheetPaymentOption.fromJson(
              json['paymentOption'] as Map<String, dynamic>),
      paymentMethod: json['paymentMethod'] == null
          ? null
          : PaymentMethod.fromJson(
              json['paymentMethod'] as Map<String, dynamic>),
      error: json['error'] == null
          ? null
          : StripeError<dynamic>.fromJson( // ------- here
              json['error'] as Map<String, dynamic>),
    );

strangely on the debugger the field seems to be a map but the code still except with this message:

[log] type 'String' is not a subtype of type 'Map<String, dynamic>' in type cast
[log] _TypeError (type 'String' is not a subtype of type 'Map<String, dynamic>' in type cast)

To Reproduce Steps to reproduce the behavior:

1. Create customer sheet
2. Create payment method
3. close
4. open customer sheet
5. click on the X button.
6. the error field fails to be converted to map

Expected behavior should not except

this seems to be because error field needs to be decoded before?

I cannot reproduce it on the example app what is the version that you are using?
