maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. List<String> tags,
    2. String? summary,
    3. String? description,
    4. ExternalDocs? externalDocs,
    5. String? operationId,
    6. List<Parameter> parameters,
    7. RequestBody? requestBody,

    10. bool? deprecated,
    11. List<Server>? servers,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( List<String> tags,  String? summary,  String? description,  ExternalDocs? externalDocs,  String? operationId,  List<Parameter> parameters,  RequestBody? requestBody,  Map<String, Response> responses,  List<SecurityRequirement> security,  bool? deprecated,  List<Server>? servers)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Operation() when $default != null:
return $default(_that.tags,_that.summary,_that.description,_that.externalDocs,_that.operationId,_that.parameters,_that.requestBody,_that.responses,_that.security,_that.deprecated,_that.servers);case _:
  return orElse();
