when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? operationRef,
    2. String? operationId,
    3. Map<String, dynamic>? parameters,
    4. dynamic requestBody,
    5. String? description,
    6. Server? server,
    )
)

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? operationRef,  String? operationId,  Map<String, dynamic>? parameters,  dynamic requestBody,  String? description,  Server? server)  $default,) {final _that = this;
switch (_that) {
case _Link():
return $default(_that.operationRef,_that.operationId,_that.parameters,_that.requestBody,_that.description,_that.server);case _:
  throw StateError('Unexpected subclass');

}
