I want to disable left and right gesture navigation for 1 page ( one dart program) in my app which is 21 dart programs. I do not care about the other pages. I have not found any simple examples that work on my pixel 8 phone.

The app compiles and works fine but I cannot disable the left and right gestures on the pixel 8 phone on which I am testing. If I add the line of code

PopScope(child: Scaffold(), canPop: false);

in the widget build override, it makes no difference – the left and right gestures are still not disabled.

Here is my code for Page6.dart (with many of the 300 lines removed for simplicity)….

class Page6 extends StatefulWidget {

...(code)

  @override
  State<Page6> createState() => _Page6State();
}

class _Page6State extends State<Page6> {

...(code)

  @override
  void initState() {

...(code)

  }


  @override
  Widget build(BuildContext context) {
    PopScope(child: Scaffold(), canPop: false);
    ManTrack mantrack = widget.mantrack;
    RouteDataModel routeNow = widget.routeNow;
    TransformationController viewTC = widget.viewTC;
    print('page6.dart - build method called, ok = $ok');
    t.timestamp('#3 ***** START BUILD *******');
    WidgetsBinding.instance.addPostFrameCallback((_) {
      t.timestamp("#999 **** BUILD COMPLETE *******");
    });
    if (ok && mantrack.uiShow != null) {
      return Scaffold(
          appBar: AppBar(
              title: const Text("Tracking You"),
              automaticallyImplyLeading: false,
              actions: [
                ElevatedButton(
                    child: Text('Refresh'),
                    style: ElevatedButton.styleFrom(
                      backgroundColor: Colors.orange,
                    ),
                    onPressed: () async {
                      getLocationNow();
                    }),
                ElevatedButton(

                      GPSLocation gpsNow = widget.gpsNow;
