whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String $type,
    2. ActorStatusStatus status,
    3. UActorStatusEmbed? embed,
    4. int? durationMinutes,
    5. DateTime createdAt,
    6. 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, @ActorStatusStatusConverter()  ActorStatusStatus status, @UActorStatusEmbedConverter()  UActorStatusEmbed? embed,  int? durationMinutes,  DateTime createdAt,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _ActorStatusRecord() when $default != null:
return $default(_that.$type,_that.status,_that.embed,_that.durationMinutes,_that.createdAt,_that.$unknown);case _:
  return null;

}
}
