maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String id, String object, @JsonKey.new(name: "address_city") String? addressCity, @JsonKey.new(name: "address_country") String? addressCountry, @JsonKey.new(name: "address_line1") String? addressLine1, @JsonKey.new(name: "address_line1_check") VerificationCheck? addressLine1Check, @JsonKey.new(name: "address_line2") String? addressLine2, @JsonKey.new(name: "address_state") String? addressState, @JsonKey.new(name: "address_zip") String? addressZip, @JsonKey.new(name: "address_zip_check") VerificationCheck? addressZipCheck, CardTokenBrand? brand, String? country, String? currency, @JsonKey.new(name: "cvc_check") VerificationCheck? cvcCheck, @JsonKey.new(name: "dynamic_last4") String? dynamicLast4, @JsonKey.new(name: "exp_month") int? expMonth, @JsonKey.new(name: "exp_year") int? expYear, String? fingerprint, CardFundingType? funding, String? last4, Map<String, dynamic> metadata, String? name, @JsonKey.new(name: "tokenization_method") CardTokenizationMethod? tokenizationMethod,)?, { required TResult orElse(), })

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String id,  String object, @JsonKey(name: "address_city")  String? addressCity, @JsonKey(name: "address_country")  String? addressCountry, @JsonKey(name: "address_line1")  String? addressLine1, @JsonKey(name: "address_line1_check")  VerificationCheck? addressLine1Check, @JsonKey(name: "address_line2")  String? addressLine2, @JsonKey(name: "address_state")  String? addressState, @JsonKey(name: "address_zip")  String? addressZip, @JsonKey(name: "address_zip_check")  VerificationCheck? addressZipCheck,  CardTokenBrand? brand,  String? country,  String? currency, @JsonKey(name: "cvc_check")  VerificationCheck? cvcCheck, @JsonKey(name: "dynamic_last4")  String? dynamicLast4, @JsonKey(name: "exp_month")  int? expMonth, @JsonKey(name: "exp_year")  int? expYear,  String? fingerprint,  CardFundingType? funding,  String? last4,  Map<String, dynamic> metadata,  String? name, @JsonKey(name: "tokenization_method")  CardTokenizationMethod? tokenizationMethod)?  $default,{required TResult orElse(),}) {final _that = this;
