App não conecta ao servidor

Quando o app faz o hot reload aparece o seguinte erro:

ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: Exception: SocketException: Connection failed (OS Error: Network is unreachable, errno = 101), address = 192.168.0.174, port = 8080

Eu fiz o teste no postman dando get e post, e funciona corretamente. Segue o código abaixo:

import 'dart:convert';

import 'package:http/http.dart';
import 'package:http_interceptor/http_interceptor.dart';

class LoggingInterceptor implements InterceptorContract {
  @override
  Future<RequestData> interceptRequest({RequestData data}) async {
    print('url ${data.url}');
    print('headers ${data.headers}');
    print('body ${data.body}');
    return data;
  }

  @override
  Future<ResponseData> interceptResponse({ResponseData data}) async {
    print(data);
    return data;
  }

}

void findAll() async {

  final Client client = HttpClientWithInterceptor.build(interceptors: [LoggingInterceptor()]);
  final Response response = await client.get('http://192.168.0.174:8080/transactions');
  final List<dynamic> decodedJson = jsonDecode(response.body);
  print(decodedJson);

}
