too many routes for location

[ebelevics]

Here is small example that causes this issue. I have three routes /todos, /todos/:id, /todos/filters. Why when I go to "/todos/filters" it drops me this exception?
P.S. When I think more about it -> it's because "filters" is expected as :id? Shouldn't router use parameter in subroutes as last resort, giving higher priority to static addresses first?

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

void main() => runApp(App());

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

  static const title = 'GoRouter Example: Declarative Routes';

  @override
  Widget build(BuildContext context) => MaterialApp.router(
        routeInformationParser: _router.routeInformationParser,
        routerDelegate: _router.routerDelegate,
        title: title,
      );

  final _router = GoRouter(
    initialLocation: "/todos",
    routes: [
      GoRoute(
        path: '/todos',
        builder: (context, state) => const Page1Screen(),
        routes: [
          GoRoute(
            path: ':id',
            builder: (context, state) => const Page2Screen(),
          ),
          GoRoute(
            path: 'filters',
            builder: (context, state) => const Page3Screen(),
          ),
        ],
      ),
    ],
  );
}

class Page1Screen extends StatelessWidget {
  const Page1Screen({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) => Scaffold(
        appBar: AppBar(title: const Text(App.title)),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              ElevatedButton(
                onPressed: () => context.push('/todos/12'),
                child: const Text('Go to details'),
              ),
              ElevatedButton(
                onPressed: () => context.push('/todos/filters'),
                child: const Text('Go to filters'),
              ),
            ],
          ),
        ),
      );
}

class Page2Screen extends StatelessWidget {
  const Page2Screen({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) => Scaffold(
        appBar: AppBar(title: const Text(App.title)),
        body: const Center(
          child: Text("details"),
        ),
      );
}

class Page3Screen extends StatelessWidget {
  const Page3Screen({Key? key}) : super(key: key);

  @override

        appBar: AppBar(title: const Text(App.title)),

        ),
      );
}

The reason you're having trouble is that /todos/filter is matching the regular expression for :id and filter. If you'd like to make the pattern for :id more restrictive, you shouldn't have that problem, e.g. path: r':id(\d+)'. You can see the path_to_regexp docs for more details (GR uses path_to_regexp to implement it's path parsing).
