UserEmailOption constructor
Implementation
const UserEmailOption({
super.argPos,
super.mandatory,
}) : super(
argName: 'user',
argAbbrev: 'u',
customValidator: emailValidator,
// a bit convoluted due to Dart's const requirements:
helpText: 'The user email address.'
'${argPos == 0 ? ' Can be passed as the first argument.' : argPos == 1 ? ' Can be passed as the second argument.' : ''}',
);
