whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. int? runId,
    2. int? jobId,
    3. int? chunk,
    4. String? name,
    5. ModelUri? downloadUrl,
    6. String text,
    7. ModelTimestamp? createdAt,
    8. bool fromServer,
    )?
)

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(
          int? runId,
          int? jobId,
          int? chunk,
          String? name,
          ModelUri? downloadUrl,
          String text,
          ModelTimestamp? createdAt,
          bool fromServer)?
      $default,
) {
  final _that = this;
  switch (_that) {
    case _GithubActionsLogModel() when $default != null:
      return $default(_that.runId, _that.jobId, _that.chunk, _that.name,
          _that.downloadUrl, _that.text, _that.createdAt, _that.fromServer);
    case _:
      return null;
