Failed assertion: line 2283 pos 14: '_debugSubtreeRelayoutRootAlreadyMarkedNeedsLayout()': is not true #147452

Open premiumbiscuit opened 2 weeks ago

premiumbiscuit commented 2 weeks ago

Steps to reproduce

I have attached a sample code to reproduce the bug. Click the "crash me!" button twice. This issue seems to disappear when the layout builder is removed.

Expected results

The counter should increment without any crashes.

Actual results

A crash occurs.

Code sample

@premiumbiscuit You are using flutter_bloc which is community package. In order to properly address the issue, please narrow down the code sample to minimal but complete and without community package implementation, that still triggers the reported exception.

Thanks @darshankawar for looking into this. I have replaced flutter_bloc with a StreamController, please see the code below. Ultimately, anything that causes re-rendering will produce the bug for some reason.

Code sample ```dart import 'dart:async'; import 'package:flutter/material.dart'; import 'package:go_router/go_router.dart'; final GlobalKey _rootNavigatorKey = GlobalKey(debugLabel: 'root'); final GlobalKey _sectionANavigatorKey = GlobalKey(debugLabel: 'sectionANav'); class CounterStream { final _stateController = StreamController.broadcast(); int _counter = 0; Stream get stateStream => _stateController.stream.asBroadcastStream(); void increment() { _stateController.sink.add(++_counter); } void dispose() { _stateController.close(); } } final CounterStream counterStream = CounterStream(); void main() { runApp(NestedTabNavigationExampleApp()); } /// An example demonstrating how to use nested navigators class NestedTabNavigationExampleApp extends StatelessWidget { /// Creates a NestedTabNavigationExampleApp NestedTabNavigationExampleApp({super.key}); final GoRouter _router = GoRouter( navigatorKey: _rootNavigatorKey, initialLocation: '/a/details', routes: [ StatefulShellRoute.indexedStack( builder: (BuildContext context, GoRouterState state, StatefulNavigationShell navigationShell) { // Return the widget that implements the custom shell (in this case // using a BottomNavigationBar).

Thank you for the report. To debug this it would help if you could reduce the test case more, see https://github.com/flutter/flutter/wiki/Issue-hygiene#provide-reduced-test-cases

I tried to come up with reduced repro code as below without go_router implementation but it is giving me different error, so probably @premiumbiscuit please try to narrow down the code to bare minimum that still triggers the reported error.
