Flutter connection to a local api

Question

m hosting a c# api locally on my machine , while trying to connect to it from my flutter app i kept getting a timeout . This is not my first time trying to connect to a local api so i know that i have to use my private ip address instead of localhost . Tried to shutdown my firewall but when shutting my public network firewall i started to get a connection refused exception(No idea why).The api is working since i tested it with postman.Any help is appreciated and thank u.

This is my screen code:

// Boutons pour choisir les images

        },
      ),
    );
  }
}

And this is method where m calling the api:

import 'dart:convert';
import 'dart:io';

import 'package:http/http.dart' as http;
import 'package:orange_app/models/pointage_model.dart';
import 'package:orange_app/models/vente_model.dart';

import '../global/config/api_connection.dart';

class PointageApi {

  static Future<http.Response> createPointage(PointageModel model) async {
    var url =Uri.http(Api.apiUrl,Api.baseUrl+Api.addPointage);
    var request = http.MultipartRequest('POST', url);

    // ... (autres parties du code sont inchangées)
    request.fields['nom'] = model.nom;
    request.fields['prénom'] = model.prenom;
    request.fields['IdUserTerrain'] = model.idUserTerrain.toString();
    request.fields['longitude'] = model.longitude.toString();
    request.fields['latitude'] = model.latitude.toString();
    request.fields['date_Pointage'] = model.datePointage.toIso8601String();
    // Ajout des images
    if (model.faceImage!= null) {
      var faceImageBytes = await model.faceImage!.readAsBytes();
      request.files.add(http.MultipartFile.fromBytes(
        'FaceImage',
        faceImageBytes,
        filename: 'faceImage'
      ));
    }

    // Vérifier si aucune image n'est enregistrée
    if (model.faceImage == null) {
      print('Image not uploaded');
    }
    print(request.fields);
    var response = await http.Response.fromStream(await request.send());
    return response;
  }
}

And finally this is the error(or part of it):
