go_router using browser back button extra is null flutter web

let’s say I navigate from page a with context.push() and pass extra to page b.
then if I navigate to page c and then press the browser back button to go back to page b now extra is null and page shows error.
any solutions?
I think we can use query parameters but it brings up security problems.

    You can follow one of the two possible solution:

    1. Dont let page to come back to B from C, You can use something like popUntil
    2. When coming back to B from C override the naviagetion such that you send the extra object along with it. So that B has extra value

    Edit:

    Presently there is no way to achieve this using go_router. You can use go_router_flow which is exactly like go_router with this pop with value feature.

    final bool? result = await context.push<bool>('/page2');

WidgetsBinding.instance.addPostFrameCallback((_) {
  if(result){
    print('Page returned $result');
  }
});
