maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. int id,
    2. String name,
    3. int suiteID,
    4. List<int> groupIDs,
    5. int? line,
    6. int? column,
    7. String? url,
    8. int? rootLine,
    9. int? rootColumn,
    10. String? rootUrl,
    11. TestMetadata metadata,
    )?, {
  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();
}
