• Uri with empty queryParameter has an extra ? at the end #122089
• Create an issueUri with empty queryParameter has an extra ? at the end dart-lang/sdk#51656

With the code generated by go_router_builder, when a route has an empty iterable (which can happen a lot when there is a default value), it always includes {} or [] in the query parameters which leads to a trailing ? at the end of the URL.
Is it possible to not include an empty iterable in the query parameters to avoid this behavior?

Steps to reproduce

1. Run flutter run on the code sample given below
2. Notice the print is /?

Expected results

I would expect the location to not have the extra ? if there are no parameters to specify

Actual results

The location ends with a ? and has not query parameters after.

Code sample

# main.dart

void main() {
  print(const MyRoute().location);
}

# pages.dart

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

part 'pages.g.dart';

@TypedGoRoute<MyRoute>(path: '/')
class MyRoute extends GoRouteData {
  const MyRoute({
    this.params = const [],
  });

  final List<int> params;

  @override
  Widget build(BuildContext context, GoRouterState state) {
    return const Placeholder();
  }
}
