## Architecture overview

```
Your Flutter app
       │
       ├── XRayNetworkInspector   ◄── XRayNetworkDioInterceptor
       ├── XRayLogInspector
       ├── XRaySharedPreferencesInspector
       └── XRaySecureStorageInspector
                        │
              XRayInspectorServer  (HTTP + WebSocket + UDP discovery)
                        │
                  xRay Inspector App / Web App
```

The inspector server runs inside your app and broadcasts data over HTTP/WebSocket. Connect to it using the xRay app or web app.

## Design principles

- **No singletons** — all dependencies are passed explicitly via constructors.
- **No disk I/O** — all captured data lives in memory only.
- **Composable** — add only the inspectors you need.
