Refactor URL logic

[alexeyinkin]

Steps to reproduce:

1. Open any package stats: https://pubstats.dev/#/packages/cupertino_icons
2. Edit the URL in the address bar to change the package name
3. Press Enter

Expected: Navigated to the new package.
Actual: The URL change is reverted, still viewing the old package.

The problem is from not using Navigator 2.0, and because the URL is parsed only once in DataController.create() in main().

This one I can fix if you approve my package for routing: https://pub.dev/packages/app_state

If you care about maintainability, the largest app it was used is Apache Beam Playground: https://play.beam.apache.org
Approved by their engineers, no problems so far.

I tried looking into this but gave up for now. Is it possible to have the navigation route update without actually pushing a new page? The entire app is actually just on one route.

[Rexios80]

Or is it possible to listen for URL changes outside of the router?

[alexeyinkin]

In theory, it is possible to listen to the URL change and do something instantly, and that is what Navigator 2.0 is all about. However, in my apps I have seen it reloading the app at the given URL, which is still better than reverting the change. I did not investigate further because reloading was OK for me.

I'm fine with the page reloading when the URL is manually changed, but what I don't want is the app to try and navigate between states when the route is updated by the UI

[alexeyinkin]

No, programmatic updates of the address bar do not cause reload with Navigator 2.0, just like it is the case now in the app.

[Rexios80]

What I'm saying is if we wanted to use the navigator to go from package1 to package2 and we did Navigator.pushNamed('/packages/package2') would it be possible for that call to update the route and NOT actually navigate

[Rexios80]

This should be fixed on https://beta.pubstats.dev. Let me know if it works for you.

Hey the navigation buttons work too and all I had to do was bypass the Flutter Navigator entirely 🙃

Closing since this appears to work
