Hello everyone hope you are great, I run the app on an emulator device in android studio, and it works fine, but with a real device I can't, it shows “we did not get any data”, tell me what do you need to solve this problem, because a have a lot of code and don't know what to show you and most importantly what file of code matters to fix this error, so please tell me if you need something and I sent to you.
I tried to run the app in a Samsung s9
this is my service.dart
import 'package:flutter/foundation.dart';
import 'package:flutter_golang_yt/colors/app_constants.dart';
import 'package:get/get.dart';

Future<Response> getData(String uri)async{
if (kDebugMode) {
print(AppConstants.BASE_URL+uri);
}
Response response=await get(
AppConstants.BASE_URL+uri,
headers: {
'Content-Type':'application/json; charset=UTF-8'
}
);
return response;
}
Future<Response> postData(String uri, dynamic body)async{
Response response=await post(
AppConstants.BASE_URL+uri,
body,
headers: {
'Content-Type':'application/json; charset=UTF-8'
}
);
return response;
}
Future<Response> updateData(String uri, dynamic body)async{
Response response=await put(
AppConstants.BASE_URL+uri,
body,
headers: {
'Content-Type':'application/json; charset=UTF-8'
}
);
return response;
}
Future<Response> deleteData(String uri)async{
Response response=await delete(
AppConstants.BASE_URL+uri,
headers: {
'Content-Type':'application/json; charset=UTF-8'
}
);
return response;
