Implementation

V? findValueOf<V>({
  final String? enumName,
  final String? argName,
  final int? argPos,
  final String? envName,
  final String? configKey,
}) {
  final option = findOption(
    enumName: enumName,
    argName: argName,
    argPos: argPos,
    envName: envName,
    configKey: configKey,
  );
  if (option == null) return null;
  return optionalValue<V>(option as OptionDefinition<V>);
