A lightweight Flutter application that fetches the device’s public IP address by leveraging native iOS networking (via NSURLSession) that respects system-level proxies and tunnels like Safari does.
This app helps detect the actual public IP used by the device — whether it's using a direct internet connection or a tunnel (e.g., VPN, PAC proxy, or local proxy server). It’s especially useful when you're working in cloud environments or dynamic networks.
- Flutter UI uses a platform channel to invoke a native Swift method.
- Native iOS code performs an HTTP request to
https://api.ipify.org. - The request is routed via
URLSession.shared, which is proxy-aware. - The public IP returned matches what Safari sees (not just raw device IP).
- ✅ Accurate public IP retrieval via proxy/tunnel
- ✅ Respects system-wide proxy config
- ✅ Native implementation for high accuracy
- ✅ Clean, minimal UI
