I'm getting a similar error on a different IP:

SocketException: Failed host lookup: 'http://10.0.2.2:8080/stomp' (OS Error: No address associated with hostname, errno = 7)

I was getting a similar issue with authentication. The following did the trick for me with Spring Security and JWT-based authentication.

Update the modified version custom_stomp posted here (thx for that @xbassols!) as follows:

Future<StompClient> connect(String url,
    {String host,
      String login,
      String passcode,
      Map<String, dynamic> headers, // <--- here
      List<int> heartbeat,
      void onConnect(StompClient client, Map<String, String> headers), // <--- here
      void onDisconnect(StompClient client),
      void onError(StompClient client, String message, String detail,
          Map<String, String> headers),
      void onFault(StompClient client, error, stackTrace)}) async =>
    connectWith(await IOWebSocketChannel.connect(url,
        headers: headers), // <--- and here
        host: host,
        login: login,
        passcode: passcode,
        heartbeat: heartbeat,
        onConnect: onConnect,
        onDisconnect: onDisconnect,
        onError: onError,
        onFault: onFault);

Then you can pass authentication headers on connect.

Future<StompClient> clientFuture = customStomp.connect(
        'ws://localhost:8080/ws',
        headers: {'Authorization': 'Bearer $accessToken'},
        onConnect: ...

Then these headers will be intercepted by Spring to perform authentication. Hope it helps!
