in a web app with beamer, the web browser back button does not work correctly.

When I run the beamer version for the web and google chrome, I can switch between the details screens A and B and the counters that they display are independent and are not lost when I switch between the two details screens using the bottom navigation buttons. Each time I switch, the URL in the browser address bar changes between a and b
http://localhost:64367/#/a/details
http://localhost:64367/#/b/details
but when I look in the browser back button history it shows "Details B" a lot instead of alternating. If I select the first one in the list, the URL changes from B to A but the screen itself stays on "details B". Sometimes when I click the browser back button the details screen does change from B to A (along with the URL) but the counter on screen A gets reset to zero.

@graemep-nz @bizz84 I saw the same issue. Can this be resolved? Is a Flutter problem, package problem or app problem?

I add a demo I recorded to show the issue with a different perspective. As we can see, the state is preserved while we navigate through the bottom navigation buttons but once we click on browser back button the state is lost.
