[go_router] fix Popping state and re-rendering scaffold at the same time doesn't update the URL on web [new]

[ahyangnb]

the old pr #6953

Change the 3 files of lib and add a example, because issue flutter/flutter#150312

The reason for the issue is when call counterStream.increment(); will notify notifyListeners() of StreamListener, and finally affect _handleRouteInformationProviderNotification of _RouterState in packages/flutter/lib/src/widgets/router.dart.

When pop should not call _handleRouteInformationProviderNotification otherwise will be path wrong.
because the value of GoRouteInformationProvider is not the latest.

Solution:

always make the value of GoRouteInformationProvider knew the latest RouteInformation[but not to do notifyListeners()].

i don't know if adding pop to NavigatingType is reasonable, if any place needs to be changed please tell me.

Result:

After changed, the issue been solved and all the others pop not be affect such as drawer/dialog/bottomsheet, See the video below.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.
