title: device info package in flutter
body: <p>i have a small doubt. In this package, there is a function that returns a 'unique' id . This is the small code: </p>
  
  <pre><code>getDevice() async{
  
  
      DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
      AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
  
      var brand = androidInfo.id;
  
      setState(() {
            info = brand;
  
            });
  
  }
  </code></pre>
  
  <p>it return me <code>PSR1.180720.093</code> as id. My doubt is, when I create another <code>virtual_device</code> (the same model with other name), and I execute the code, it returns <code>PSR1.180720.093</code>, the same. This code returns a real unique id? Why is it returning the same id in two different devices?</p>
