awaiting the dialog results in stuck state

[Mikkelet]

If you modify the will pop scope function to await the result from the dialog and pop/stay based on the result, the page can get stuck in a stuck state.

Modify the example as such:

Future<bool> _onWillPop() async {
    if (_hasChanges) {
    // Show an alert before returning false
    final response = await showDialog(
        context: context,
        builder: (context) => _dialog(context),
      );
      print("response=$response");
      return response;
    }

    return true;
   }

and add this:

Widget _dialog(BuildContext context) {
    return Dialog(
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
          MaterialButton(
            onPressed: () {
              Navigator.of(context).pop(true);
            },
            child: Text("Pop"),
          ),
          MaterialButton(
            onPressed: () {
              Navigator.of(context).pop(false);
            },
            child: Text("Dont pop"),
          ),
        ],
      ),
    );
  }

The result returns fine, but the page does not respond. If you select "dont pop", the page can get stuck and you cannot swipe to go back
