when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String userId,
    2. String displayName,
    3. String certificationId,
    4. String certificationName,
    5. String status,
    6. DateTime? issuedAt,
    7. DateTime? expiresAt,
    8. DateTime? deadline,
    )
)

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 userId,  String displayName,  String certificationId,  String certificationName,  String status,  DateTime? issuedAt,  DateTime? expiresAt,  DateTime? deadline)  $default,) {final _that = this;
switch (_that) {
case _ComplianceStatusEntry():
return $default(_that.userId,_that.displayName,_that.certificationId,_that.certificationName,_that.status,_that.issuedAt,_that.expiresAt,_that.deadline);case _:
  throw StateError('Unexpected subclass');

}
