when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? cursor,
    2. int? hitsTotal,
    3. @PostViewConverter() List<PostView> posts,
    4. @FeedSearchPostsV2DetectedQueryLanguagesConverter() List<FeedSearchPostsV2DetectedQueryLanguages>? detectedQueryLanguages,
    5. 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? cursor,  int? hitsTotal, @PostViewConverter()  List<PostView> posts, @FeedSearchPostsV2DetectedQueryLanguagesConverter()  List<FeedSearchPostsV2DetectedQueryLanguages>? detectedQueryLanguages,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _FeedSearchPostsV2Output():
return $default(_that.cursor,_that.hitsTotal,_that.posts,_that.detectedQueryLanguages,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
}
