I’m building a Flutter app that discovers a local device over Wi-Fi and calls its local REST API.

On Xiaomi/Redmi (MIUI), local mode fails with DNS resolution for .local hostnames, while the same flow works on other Android devices.

I can make it work using direct IP, but I want to use hostname because IP may change (DHCP/network changes).

Error log:

[RESPONSE] [REST REQUEST] ************* ERROR *************
           {
             "method": "GET",
             "url": "https://type-macaddres.local/...",

             "error": "SocketException: Failed host lookup: 'type-macaddres.local' (OS Error: No address associated with hostname, errno = 7)",

               }
             }
           }
           *********************************

What I’m using in Flutter:

• nsd package for service discovery (DNS-SD/mDNS), service type like _name_secondaname._tcp

• dart:io HttpClient for REST requests

• connectivity_plus for connection state

• Discovery with autoResolve: true and ipLookupType: IpLookupType.any

Example discovery call:

final discovery = await startDiscovery(
  '_name_secondaname._tcp.',
  autoResolve: true,
  ipLookupType: IpLookupType.any,
);

Context:

• Flutter app (Android)

• Request to http(s)://<device-name>.local/...

• Fails only on Xiaomi/Redmi (MIUI)

Already checked:

• Android permissions: INTERNET, ACCESS_NETWORK_STATE, CHANGE_WIFI_MULTICAST_STATE

• Private DNS on/off

• MIUI battery/data restrictions disabled

• ipLookupType: any

Questions:

1. Is this a known MIUI limitation with resolving .local hostnames from Flutter/Dart HttpClient?

2. Is using direct IP the only reliable approach on Xiaomi?

3. Any Xiaomi-specific workaround that reliably fixes mDNS hostname resolution?

NOTE: I've all the manifest permissions, and have done everything that could find, wich not worked. NOTE #2: I'm testing with real device (Xiaomi Redmi 8T)
