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

class PlatformUtils {
static bool _isWeb() {
return kIsWeb == true;
}

static bool _isAndroid() {
return _isWeb() ? false : Platform.isAndroid;
}

static bool _isIOS() {
return _isWeb() ? false : Platform.isIOS;
}

static bool _isMacOS() {
return _isWeb() ? false : Platform.isMacOS;
}

static bool _isWindows() {
return _isWeb() ? false : Platform.isWindows;
}

static bool _isFuchsia() {
return _isWeb() ? false : Platform.isFuchsia;
}

static bool _isLinux() {
return _isWeb() ? false : Platform.isLinux;
}

static bool get isWeb => _isWeb();

static bool get isAndroid => _isAndroid();

static bool get isIOS => _isIOS();

static bool get isMacOS => _isMacOS();

static bool get isWindows => _isWindows();

static bool get isFuchsia => _isFuchsia();

static bool get isLinux => _isLinux();
}
