whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. AtUri uri,
    2. String? cid,
    3. String? cursor,
    4. List<Like> likes,
    5. 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(@AtUriConverter()  AtUri uri,  String? cid,  String? cursor, @LikeConverter()  List<Like> likes,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _FeedGetLikesOutput() when $default != null:
return $default(_that.uri,_that.cid,_that.cursor,_that.likes,_that.$unknown);case _:
  return null;

}
}
