[go_router] 5.2.0 push doesn't update the URL anymore.

[ValentinVignal]

Steps to Reproduce

1. Execute flutter run on the code sample (see "Code sample" section below)
2. Click on the button "Settings" to push the settings page
3. Notice the URL didn't change when using go_router 5.2.0

Expected results:

I expect the URL to change

Actual results:

The URL didn't change

---

The issue doesn't happen in the previous version (5.1.10) so I believe this was introduced in flutter/packages#2786

I don't know if this is related to #99112 (comment) which plans to remove imperative methods. But since I didn't see anything in the changelogs or documentation, I'm assuming this is a regression.

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

final router = GoRouter(
  routes: [
    GoRoute(
      path: '/',
      builder: (context, state) => const Home(),
    ),
    GoRoute(
      path: '/settings',
      builder: (context, state) => const Settings(),
    ),
  ],
);

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      routerConfig: router,
    );
  }
}

class Home extends StatelessWidget {
  const Home({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Home'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            router.push('/settings');
          },
          child: const Text('Settings'),
        ),
      ),
    );
  }
}

class Settings extends StatelessWidget {
  const Settings({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Settings'),
      ),

Triage report

I can reproduce this issue. I can also confirm that the URL does indeed change in 5.1.10 but not in 5.2.0. Labeling as regression

Code Sample (Same as OP)

import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';

void main() {
  runApp(const MyApp());
}

final router = GoRouter(
  routes: [
    GoRoute(
      path: '/',
      builder: (context, state) => const Home(),
    ),
    GoRoute(
      path: '/settings',
      builder: (context, state) => const Settings(),
    ),
  ],
);

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      routerConfig: router,
    );
  }
}

class Home extends StatelessWidget {
  const Home({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Home'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            router.push('/settings');
          },
          child: const Text('Settings'),
        ),
      ),
    );
  }
}

class Settings extends StatelessWidget {
  const Settings({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Settings'),
      ),
    );
  }
}

Yeah I'm facing the same issue when pushing the route URl is not updating. In mobile app using context.go going to the route but once I back to previous route then I can't longer go to same route again.

[s9th]

context.pop() also doesn't update URL. Maybe it's a consequence, maybe it's the same root cause.

[tolo]

It's related to the changes in RouteMatchList in 5.2.0. Previously, the location was calculated based on the RouteMatches, like this:

Uri get location =>
      _matches.isEmpty ? Uri() : Uri.parse(_matches.last.fullUriString);

But in 5.2.0, location was replaced with an uri field (final Uri uri) that is only set at the initial creation of the RouteMatchList, and never updated when pushing/popping.

[tolo]

Reading the discussion in #99112 I realise there are more complexity to consider, and I sort of understand the reasoning around that pushed routes perhaps doesn't justify a location change. However, I think pop is a bit different, since that operation is often performed indirectly via BackButtons etc (perhaps mostly mobile though, but perhaps not only), and it's performed for both pushed and "go:ed" routes. Perhaps the pop method in RouterDelegate needs to take into account if the last RouteMatch was an ImperativeRouteMatch or not, and apply different handling?

@chunhtai may i know any status update or any schedule plan about this issue?

[chunhtai]

I plan to work on this soon.
