when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. int? number,
    2. String? name,
    3. String? status,
    4. String? conclusion,
    5. ModelTimestamp? startedAt,
    6. ModelTimestamp? completedAt,
    )
)

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(
          int? number,
          String? name,
          String? status,
          String? conclusion,
          ModelTimestamp? startedAt,
          ModelTimestamp? completedAt)
      $default,
) {
  final _that = this;
  switch (_that) {
    case _GithubActionsStepValue():
      return $default(_that.number, _that.name, _that.status,
          _that.conclusion, _that.startedAt, _that.completedAt);
    case _:
      throw StateError('Unexpected subclass');
  }
