when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String deliveryNumber,
    2. String phSSCCNumber,
    3. List<String> ssccList,
    4. Delivery? delivery,
    5. List<HuDetails?> ssccDetails,
    )
)

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 deliveryNumber,  String phSSCCNumber,  List<String> ssccList,  Delivery? delivery,  List<HuDetails?> ssccDetails)  $default,) {final _that = this;
switch (_that) {
case _DeliveryBundle():
return $default(_that.deliveryNumber,_that.phSSCCNumber,_that.ssccList,_that.delivery,_that.ssccDetails);}
}
