I'm using go_router to build an application that
does "dummy" pushes of routes (a bit like Twitter). It is possible to start with a page /a ,push /b, then /c, ... and then push again /a.
When a page is pushed twice, an assert fails: assert(!keyReservation.contains(key)); which ensures a key is used only once in the Navigator.
Is there a way to be able to push twice the same page with go_router?
Here is a small code snippet:
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
void main() {
runApp(const MyApp());
}
final router = GoRouter(
initialLocation: '/a',
routes: [
GoRoute(
path: '/a',
builder: (_, __) => const MyWidget(path: '/a'),
),
GoRoute(
path: '/b',
builder: (_, __) => const MyWidget(path: '/b'),
),
],
);
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp.router(
routeInformationProvider: router.routeInformationProvider,
routeInformationParser: router.routeInformationParser,
routerDelegate: router.routerDelegate,
);
}
}
class MyWidget extends StatelessWidget {
const MyWidget({
required this.path,
Key? key,
}) : super(key: key);
final String path;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(path),
),
body: Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
TextButton(
onPressed: () {
context.push('/a');
},
child: const Text('/a'),
),
TextButton(
onPressed: () {
context.push('/b');
},
child: const Text('/b'),
),
],
)),
);
}
}
The issue can be triggered by clicking on the TextButton with "/a".
