//import 'dart:io';
import 'package:flutter/foundation.dart';
//import 'package:universal_io/io.dart';
import 'dart:ui';

double deviceWidth(Size size) {
if (defaultTargetPlatform == TargetPlatform.windows ||
defaultTargetPlatform == TargetPlatform.linux ||
defaultTargetPlatform == TargetPlatform.macOS) {
return size.width;
