whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String $type,
    2. AtUri uri,
    3. String cid,
    4. Map<String, dynamic> value,
    5. List<BlobView> blobs,
    6. List<Label>? labels,
    7. DateTime indexedAt,
    8. ModerationDetail moderation,
    9. RepoView repo,
    10. Map<String, dynamic>? $unknown,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String $type, @AtUriConverter()  AtUri uri,  String cid,  Map<String, dynamic> value, @BlobViewConverter()  List<BlobView> blobs, @LabelConverter()  List<Label>? labels,  DateTime indexedAt, @ModerationDetailConverter()  ModerationDetail moderation, @RepoViewConverter()  RepoView repo,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _RecordViewDetail() when $default != null:
return $default(_that.$type,_that.uri,_that.cid,_that.value,_that.blobs,_that.labels,_that.indexedAt,_that.moderation,_that.repo,_that.$unknown);case _:
  return null;
