Swipe back in flutter. without any button

How Can I swipe for back in Flutter? not tap back button.
Without any button……
Just swipe from left to right. And go to the back page

>Solution :

you can wrap your screen widget with gesture detector and on detecting swipe left you can pop the screen like this

GestureDetector(
  onPanUpdate: (details) {
    if (details.delta.dx > 0) {
      Navigator.of(context).pop();
    }
  },
  child: Scaffold(
    body: ///your body
  ),
);

Edit:

The above solution was the one that came to my mind and i got another answer on stack-overflow maybe that one is the correct way to do it here is the answer
