i added this in py file

class PosOrder(models.Model):
    """To write the product addons to backend """
    _inherit = 'pos.order'

    floor_name = fields.Many2one('restaurant.floor', string='Floor')

    @api.model
    def _order_fields(self, ui_order):
        res = super(PosOrder, self)._order_fields(ui_order)
        res['floor_name'] = ui_order.get('floor_name', False)
        return res

this in js file

	​/** @odoo-module */
import Registries from 'point_of_sale.Registries';
import {Order, Orderline, PosGlobalState } from 'point_of_sale.models';

var round_pr = utils.round_precision;

const PosAddonsOrderline = (Orderline) =>
    class PosSaleOrderline extends Orderline {
	​get_floor_name() {
    const selectedTable = this.pos.tables_by_id[this.table_id];
    const selectedFloor = selectedTable ? this.pos.floors_by_id[selectedTable.floor_name[0]] : null;
    return selectedFloor ? { id: selectedFloor.id, name: selectedFloor.name } : null;
}
export_for_printing() {
    var a = {
