OptionSpec.value constructor

OptionSpec.value(String name, { required String? abbr, required bool required, required bool repeatable, })

A value option: --name value, --name=value, or -n value (never -n=value, which is not a valid short form).

Implementation

OptionSpec.value(
  this.name, {
  required this.abbr,
  required this.required,
  required this.repeatable,
}) : takesValue = true {
  _validate();
}
