when<TResult extends Object?> method
TResult
when<TResult extends Object?>()
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, List<String> signatures, List<CollectDataFieldResult>? collectedData, int? maxPollMs) $default,) {final _that = this;
switch (_that) {
case _ConfirmPaymentRequest():
return $default(_that.paymentId,_that.optionId,_that.signatures,_that.collectedData,_that.maxPollMs);}
}
