Flutter web platform check

Question

I am trying to find a way to see which platform (iOS or Android) my flutter web project is running on. When I use if (Platform.isIOS) { //do something }, I face error below:

Error: Unsupported operation: Platform._operatingSystem
at Object.throw_ [as throw] (http://localhost:44159/dart_sdk.js:4334:11)
at Function._operatingSystem (http://localhost:44159/dart_sdk.js:55064:17)

at wrapper (http://localhost:44159/dart_sdk.js:59904:30)

Is there a way?

Thanks.

try to do like this:

import 'package:flutter/foundation.dart' show kIsWeb;

if (kIsWeb) {
  //do something
}

How does this answer the question? OP is not trying to find if it's on web but in which OS it is. – Friesian

Answer 2

import 'package:flutter/foundation.dart';

if (defaultTargetPlatform == TargetPlatform.android) {
  //current platform is Android
} else if(defaultTargetPlatform == TargetPlatform.macOS){
  //current platform is macOS
}...
