maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String openapi,
    2. Info? info,
    3. List<Server> servers,
    4. Map<String, PathItem> paths,
    5. Components? components,
    6. List<SecurityRequirement> security,
    7. List<Tag> tags,

    9. @JsonKey.new(includeIfNull: false, includeFromJson: false, includeToJson: false) Map<String, dynamic>? extensions,
    )?, {
  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( String openapi,  Info? info,  List<Server> servers,  Map<String, PathItem> paths,  Components? components,  List<SecurityRequirement> security,  List<Tag> tags,  ExternalDocs? externalDocs, @JsonKey(includeIfNull: false, includeFromJson: false, includeToJson: false)  Map<String, dynamic>? extensions)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _OpenAPI() when $default != null:
return $default(_that.openapi,_that.info,_that.servers,_that.paths,_that.components,_that.security,_that.tags,_that.externalDocs,_that.extensions);case _:
  return orElse();
