    Swap out the outdated WillPopScope widget for the PopScope new widget; see the code below

    PopScope(
  canPop: true,
  onPopInvoked : (didPop){
   // Write your logic here...
  },
)

    Yes Will PopScope is deprecated and you should use popScope instead.

       PopScope(
         canPop: true,
         onPopInvoked: (didPop) => Navigator.pop(context),
         child: child),

    This is a new widget provided by flutter to handle pop scope. Simply add this to any child and implement onPopInvoked method it will give you a Boolean value which gives you feedback on whether it popped or not if yes then pop scope was invoked and you can handle action accordingly.
