when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String id,
    2. String status,
    3. bool livemode,
    4. String clientSecret,
    5. String paymentMethodId,
    6. String usage,

    8. String? description,

    10. LastSetupError? lastSetupError,
    11. NextAction? nextAction,
    12. MandateData? mandateData,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String id,  String status,  bool livemode,  String clientSecret,  String paymentMethodId,  String usage,  List<PaymentMethodType> paymentMethodTypes,  String? description,  String? created,  LastSetupError? lastSetupError,  NextAction? nextAction,  MandateData? mandateData)  $default,) {final _that = this;
switch (_that) {
case _SetupIntent():
return $default(_that.id,_that.status,_that.livemode,_that.clientSecret,_that.paymentMethodId,_that.usage,_that.paymentMethodTypes,_that.description,_that.created,_that.lastSetupError,_that.nextAction,_that.mandateData);case _:
  throw StateError('Unexpected subclass');
