    /**
     * Low-level method to indicate that a field can be empty.
     *
     * This method should generally not be used, and instead you should
     * use:
     *
     * - `allowEmptyString()`
     * - `allowEmptyArray()`
     * - `allowEmptyFile()`
     * - `allowEmptyDate()`
     * - `allowEmptyDatetime()`
     * - `allowEmptyTime()`
     *
     * Should be used as their APIs are simpler to operate and read.
     *
     * You can also set flags, when and message for all passed fields, the individual
     * setting takes precedence over group settings.
     *
     * ### Example:
     *
     * ```
     * // Email can be empty
     * $validator->allowEmptyFor('email', Validator::EMPTY_STRING);
     *
     * // Email can be empty on create
     * $validator->allowEmptyFor('email', Validator::EMPTY_STRING, Validator::WHEN_CREATE);
     *
     * // Email can be empty on update
     * $validator->allowEmptyFor('email', Validator::EMPTY_STRING, Validator::WHEN_UPDATE);
     * ```
     *
     * It is possible to conditionally allow emptiness on a field by passing a callback
     * as a second argument. The callback will receive the validation context array as
     * argument:
     *
     * ```
     * $validator->allowEmpty('email', Validator::EMPTY_STRING, function ($context) {
     *   return !$context['newRecord'] || $context['data']['role'] === 'admin';
     * });
     * ```
     *
     * If you want to allow other kind of empty data on a field, you need to pass other
     * flags:
     *
     * ```
     * $validator->allowEmptyFor('photo', Validator::EMPTY_FILE);
     * $validator->allowEmptyFor('published', Validator::EMPTY_STRING | Validator::EMPTY_DATE | Validator::EMPTY_TIME);
     * $validator->allowEmptyFor('items', Validator::EMPTY_STRING | Validator::EMPTY_ARRAY);
     * ```
     *
     * You can also use convenience wrappers of this method. The following calls are the
     * same as above:
     *
     * ```
     * $validator->allowEmptyFile('photo');
     * $validator->allowEmptyDateTime('published');
     * $validator->allowEmptyArray('items');
     * ```
     *
     * @param string $field The name of the field.
     * @param int|null $flags A bitmask of EMPTY_* flags which specify what is empty.
     *   If no flags/bitmask is provided only `null` will be allowed as empty value.
     * @param \Closure|string|bool $when Indicates when the field is allowed to be empty
     * Valid values are true, false, 'create', 'update'. If a Closure is passed then
     * the field will allowed to be empty only when the callback returns true.
