isNegateable property

bool? isNegateable
final

Can the flag be prefixed with 'no'?

This will only make sense on boolean properties that have a default to true.

@Parameter(isNegateable: true)
bool verbose = true;

On the command line, one can:

Command Line Result
empty verbose will be true
--verbose verbose will be true
--no-verbose verbose will be false

Implementation

final bool? isNegateable;
