WebView or iframe loads the widget URL

Bridge channel registered (SanalBridge for Flutter)

Handler waits for SANAL_READY, then sends SANAL_INIT and SANAL_CART_SYNC

Cart changes from the widget update your cart and re-sync

Navigation messages open the correct screens in your app

⚠️ Important timing rule

Wait for SANAL_READY before sending SANAL_CART_SYNC.

In Flutter, onPageFinished fires before the React app has mounted. Sending the cart too early will be ignored. Use SANAL_READY as the signal to sync the cart.
