Implementation

@override
Future<int> run() async {
  if (argResults!.rest.isEmpty) {
    logger.err('Branch name is required.');
    return ExitCode.usage.code;
  }

  final branchName = argResults!.rest.first;
  logger.info('Checking out new branch: $branchName');

  final result = await Process.run('git', ['checkout', '-b', branchName]);
  if (result.exitCode != 0) {
    logger.err(result.stderr as String);
    return result.exitCode;
  }

  logger.success('Switched to branch $branchName');
  return ExitCode.success.code;
}
