maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String name,
    3. String? description,
    4. @RichtextFacetConverter() List<RichtextFacet>? descriptionFacets,
    5. @AtUriConverter.new() AtUri list,
    6. @FeedItemConverter() List<FeedItem>? feeds,
    7. DateTime createdAt,
    8. Map<String, dynamic>? $unknown,
    )?, {
  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 $type,  String name,  String? description, @RichtextFacetConverter()  List<RichtextFacet>? descriptionFacets, @AtUriConverter()  AtUri list, @FeedItemConverter()  List<FeedItem>? feeds,  DateTime createdAt,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _GraphStarterpackRecord() when $default != null:
return $default(_that.$type,_that.name,_that.description,_that.descriptionFacets,_that.list,_that.feeds,_that.createdAt,_that.$unknown);case _:
  return orElse();
