Flutter Question posted in
The official Flutter documentation can be found here.

Flutter – 'WillPopScope' is deprecated and shouldn't be used

@override
Widget build(BuildContext context) {
  return WillPopScope(
    onWillPop: () async {
      await _stop(); // Stop the speech when the back button is pressed
      return true;
    },
        child: Scaffold (...),
    );
  }

The flutter code block of mine (above) shows the warning though it’s working but I want to migrate to the recommended approach. Please help me to solve this issue as I can not migrate to the recommended approach. I am having trouble with that. Android Studio message is shown below:

I’ve tried but found errors.

    Use popscope Widget Or For back_button_interceptor 7.0.3 package From pub dev

    PopScope(
  canPop: canPop,// Make it  false to Work
  onPopInvoked: (bool value) {
    setState(() {
      canPop= !value; //Logic and manage State
    });

    if (canPop) {
      ScaffoldMessenger.of(context).showSnackBar(
        const SnackBar(
          content: Text("Click once more to go back"),
          duration: Duration(milliseconds: 1500),
        ),
      );
    }
  },

    This is Example You can add Business Logic in Pop scope
