How do you detect the host platform from Dart code?

Question

For UI that should differ slightly on iOS and Android, i.e. on different platforms, there must be a way to detect

Answer 1

It is simple just import the io library

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

or in very simple way

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