Woocommerce Flutter FluxStore -- 2

We need to customize our entire login flow. We intent to use Email /Phone number & Password/ SMS OTP for login our existing customer, & create new customers using sign-up and update wpdb. I already have users on my woocommerce store and same needs to get mapped while login with firebase otp login. Need to achieve a proper login flow on fluxstore android mobile app over woocommerce using firebase or any other sms otp login provider. Currently we use smsalert for otp login and sms alert notification plugin in woocommerce. They have all the api's and sdk to integrate on a app. However codes are not specific to flutter . If we use 3rd party plugin for otp login in flutter fluxstore woocomerce we can skip firebase phone login. Need to implement one of the two solutions to have a seamless login,register process with complete sync to woocommerce db for website.
