mapFromShippingMethod on iOS produces a a dictionary with invalid types

Line 187 in e5666ee

"type": shippingMethod.type,

I'm not sure what magic is involved for this to serialize correctly on React Native but it will fail on Flutter which uses JSONSerialization.data(withJSONObject... internally and fails with:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (__SwiftValue)'
terminating with uncaught exception of type NSException
2022-11-10 13:42:08.015484+0100 Runner[22220:691507] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (__SwiftValue)'

The culprit is the line linked above where the type is serialized:

(lldb) po body
▿ 1 element
  ▿ 0 : 2 elements
    - key : "shippingMethod"
    ▿ value : 5 elements
      ▿ 0 : 2 elements
        - key : amount
        - value : 3.21
      ▿ 1 : 2 elements
        - key : label
        - value : Standard Shipping
      ▿ 2 : 2 elements
        - key : detail
        - value : Arrives by June 29
      ▿ 3 : 2 elements
        - key : identifier
        - value : standard
      ▿ 4 : 2 elements
        - key : type
        - value : __C.PKPaymentSummaryItemType(rawValue: 0)

should the line be adjusted to return type.rawValue instead?
