Answer 1

       Scaffold(
          body = PopScope(
            ///
            /// [canPop] is used to determine whether the current page can be popped or not.
            ///
            canPop: false,
            ///
            ///
            /// Called after a route pop was handled.
            /// It's not possible to prevent the pop from happening at the time that this method is called; the pop has already happened. Use [canPop] to disable pops in advance.
            /// This will still be called even when the pop is canceled. A pop is canceled when the relevant [Route.popDisposition] returns false, such as when [canPop] is set to false on a [PopScope]. The didPop parameter indicates whether or not the back navigation actually happened successfully.
            ///
            ///
            onPopInvoked: (didPop) {
             if (didPop) {
                Navigator.pop(context);
             }
            },
            child: Container(),
          ),
        )
