@override Future run()

Runs this command.

The return value is wrapped in a Future if necessary and returned by CommandRunner.runCommand.

Implementation

@override
Future run() async {
  var raw = argResults!['raw'] as bool?;
  if (raw == false) {
    print('Only supported with --raw');
    return 1;
  }
