maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String? label,
    2. String? ref,
    3. String? sha,
    4. GithubUserModelRef? user,
    5. GithubRepositoryModelRef? repo,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  TResult Function(
          String? label,
          String? ref,
          String? sha,
          @refParam GithubUserModelRef? user,
          @refParam GithubRepositoryModelRef? repo)?
      $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _GithubPullRequestHeadValue() when $default != null:
      return $default(
          _that.label, _that.ref, _that.sha, _that.user, _that.repo);
    case _:
      return orElse();
  }
}
