    $form_values = $form_state->getValues();
    $directory = $form_values['directory_name'];
    // The options passed to FileSystemInterface::prepareDirectory() are a
    // bitmask, so we can specify
    // either FileSystemInterface::MODIFY_PERMISSIONS
    // (set permissions on the directory),
    // FileSystemInterface::CREATE_DIRECTORY,
    // or both together:
    // FileSystemInterface::MODIFY_PERMISSIONS |
    // FileSystemInterface::CREATE_DIRECTORY.
    // FileSystemInterface::MODIFY_PERMISSIONS
    // will set the permissions of the directory by default to 0755,
    // or to the value of the variable
    // 'file_chmod_directory'.
