title: How to get a unique identifier for a device running a flutter web app?
body: <p>I would like to get a unique identifier like a mac address for a desktop machine running my flutter web app.</p>
  
  <p>Something similar to device Id for ioS and Android. I have tried all the available plugins but none of them return a value and I was wondering if there is such feature or is this still missing from Flutter Web</p>
