Project description:
"Overview
We need a Flutter developer experienced with FluxStore WooCommerce to implement native in-app checkout: Stripe, PayPal, Triple-A (crypto) for Android, and Apple In-App Purchase (IAP) for iOS. Backend is WooCommerce. Delivery: 5–7 days.

Must-Have Skills

Flutter & Dart (production apps)

FluxStore WooCommerce customization (beyond config)

Native payments: Stripe (PaymentIntent + 3DS), PayPal (wallet + card), Triple-A (crypto)

Apple In-App Purchase (consumables / non-consumables) setup and validation

WooCommerce REST API & webhooks

Git workflow; Android & iOS

Scope

Native Checkout UI – replace webviews with native screens.

Stripe – PaymentIntents, 3DS, declines/cancel, WooCommerce sync.

PayPal – wallet + native card, WooCommerce sync.

Triple-A – crypto invoices, QR/details in-app, webhook handling, WooCommerce sync.

iOS IAP – integrate StoreKit for Apple In-App Purchase; validate receipts, map purchases to WooCommerce orders.

Integration – correct totals, taxes, discounts; idempotent updates; offline retry.

Security – env-based keys, sandbox/prod toggles, no secrets in repo.

Delivery

Clean code via Git PR, README, test APK/IPA.

QA checklist + screencast of flows (success/cancel/decline/error).

Acceptance = Android flows work with sandbox keys; iOS IAP test purchases succeed and sync with WooCommerce.

Day 1: Setup, WooCommerce pipeline, env toggles

Day 2: Stripe native flow
