maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({ TResult cancel(Object? error, RequestOptions? options)?, TResult connectionTimeout()?, TResult sendTimeout()?, TResult receiveTimeout()?, TResult badCertificate()?, TResult connectionError()?, TResult badResponse(Response? response, int? statusCode)?, TResult businessException(String message, Object? error, StackTrace? stackTrace)?, 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
