invoke method

Object? invoke(
  1. List<Object?> arguments
)

Calls the function, collapsing the result list the way JavaScript does: no results gives null, one result gives the value itself and several results give the list.

Implementation

Object? invoke(List<Object?> arguments) {
  final results = call(arguments);
  if (results.isEmpty) return null;
  if (results.length == 1) return results.first;
  return results;
}
