Project description:
"My Flutter codebase already ships on both iOS and Android, but I still need two quick enhancements before the next release.

First, I want the existing phone-number sign-in flow to switch from SMS to a WhatsApp-based OTP. I do not yet have a provider, so please suggest a reliable WhatsApp Business API gateway and wire it into the current authentication logic. The flow should trigger the OTP, handle time-outs and retries, and cleanly surface any provider errors in the UI.

Second, every order object in the database already carries a SKU; however, that value is not being surfaced in the mobile UI. I simply need the SKU rendered in the order-details screen alongside the other item information so users can reference it easily.

Deliverables
• Working WhatsApp OTP verification fully integrated into the Flutter app (iOS & Android)
• A brief note on the chosen API provider, setup steps, and any required keys or webhooks
• Updated Flutter screen(s) showing the SKU in the order details, aligned with current design

I will test by compiling the app, receiving an OTP through WhatsApp, completing login/registration, and confirming the SKU appears correctly for existing orders. If that passes, we’re done." (client-provided description)
