when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. DateTime createdAt,
    3. AtUri post,
    4. List<AtUri>? detachedEmbeddingUris,
    5. List<UFeedPostgateEmbeddingRules>? embeddingRules,
    6. Map<String, dynamic>? $unknown,
    )
)

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 $type,  DateTime createdAt, @AtUriConverter()  AtUri post, @AtUriConverter()  List<AtUri>? detachedEmbeddingUris, @UFeedPostgateEmbeddingRulesConverter()  List<UFeedPostgateEmbeddingRules>? embeddingRules,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _FeedPostgateRecord():
return $default(_that.$type,_that.createdAt,_that.post,_that.detachedEmbeddingUris,_that.embeddingRules,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
