How do you detect the host platform from Dart code?

This custom-created class will help you to detect the platform:


````dart
import 'package:flutter/foundation.dart'
show defaultTargetPlatform, kIsWeb, TargetPlatform;

enum Os {
web,
android,
ios,
macOS,
linux,
windows,
fuchsia,
}

class Platform {
const Platform();

/// Platform is Web.
static bool get isWeb => os == Os.web;

/// Platform is Android.
static bool get isAndroid => os == Os.android;

/// Platform is IOS.
static bool get isIOS => os == Os.ios;

/// Platform is Fuchsia.
static bool get isFuchsia => os == Os.fuchsia;

/// Platform is Linux.
static bool get isLinux => os == Os.linux;

/// Platform is MacOS.
static bool get isMacOS => os == Os.macOS;

/// Platform is Windows.
static bool get isWindows => os == Os.windows;

/// Platform is Android or IOS.
static bool get isMobile => isAndroid || isIOS;

/// Platform is Android or IOS or Fuchsia.
static bool get isFullMobile => isMobile || isFuchsia;

/// Platform is Linux or Windows or MacOS.
static bool get isDesktop => isLinux || isWindows || isMacOS;

/// Getting the os name.
static Os get os {
if (kIsWeb) {
return Os.web;
}
switch (defaultTargetPlatform) {
case TargetPlatform.android:
return Os.android;
case TargetPlatform.iOS:
return Os.ios;
case TargetPlatform.macOS:
return Os.macOS;
case TargetPlatform.windows:
return Os.windows;
case TargetPlatform.fuchsia:
return Os.fuchsia;
case TargetPlatform.linux:
return Os.linux;
}
}
}
