Detect Host Platform From Dart Code

How to detect the host platform from Dart code?

As we all are aware that Flutter is a cross-platform development for natively compiled applications for mobile, web, and desktop from a single codebase. so UI that should differ slightly on iOS and Android, i.e. on different platforms, there must be a way to detect which one the app is running on.

How to detect the host platform from Dart code?

To detect the host platform from dart code users need to import a package like below:

import 'dart:io' show Platform;

Now user can identify the host platform using the code snippet as below:

if (Platform.isAndroid) {
  // Android-specific code
} else if (Platform.isIOS) {
  // iOS-specific code

Users can also detect if you are running on the web using kIsWeb, a global constant indicating if the application was compiled to run on the web.

import 'package:flutter/foundation.dart' show kIsWeb;
if (kIsWeb) {
  // running on the web!
} else {
  // NOT running on the web! You can check for additional platforms here.

Users can also import the platform package like below:

import 'dart:io' show Platform;

Now users need to identify Operating System using the code snippet as below:

String os = Platform.operatingSystem; //in your code

It is simple just to import the io library.

import'dart:io' show Platform;
void main(){
  return someThing();
}else if(Platform.isAndroid){
  return otherThing();
}else if(Platform.isMacOS){
  return anotherThing();

or in a very simple way.

Platform.isIOS ? someThing() : anOther(),

You can use the Universal Platform package

import 'package:universal_platform/universal_platform.dart';
bool isIos = UniversalPlatform.isIOS;
bool isAndroid = UniversalPlatform.isAndroid;
bool isWeb = UniversalPlatform.isWeb;
print('iOS: $isIos');
print('Android: $isAndroid');
print('Web: $isWeb');
