when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String paymentId,
    2. String optionId,
    3. @Deprecated('Use data instead') List<String> signatures,
    4. List<Object>? data,
    5. List<CollectDataFieldResult>? collectedData,
    6. int? maxPollMs,
    )
)

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 paymentId,  String optionId, @Deprecated('Use data instead')  List<String> signatures,  List<Object>? data,  List<CollectDataFieldResult>? collectedData,  int? maxPollMs)  $default,) {final _that = this;
switch (_that) {
case _ConfirmPaymentRequest():
return $default(_that.paymentId,_that.optionId,_that.signatures,_that.data,_that.collectedData,_that.maxPollMs);}
}
