Crash on termination in iOS on 2.8.0 and greater

Since 2.8.0 (also 2.8.1, 2.9.0), I consistently get a crash report (see below) after terminating an app on iOS (both real device through TestFlight in release mode and simulator). Note that this is the case even with a new default template counter app, a fresh flutter install, and even when building an app in a GitHub workflow (so not on my machine).

Steps to Reproduce

Start an iOS simulator (I used iOS 15.2 on iPhone 13, but had the same problem on a real device on 15.2)
Execute flutter run on the code sample (default template counter app)
Terminate the app (swipe it away).

Expected results:
The app closes and nothing happens.

Actual results:
The app closes and a few seconds later, a crash log appears. On my real iOS device, I instantly get a popup saying that the app crashed, but no report. Hence I added instructions and log for a simulator.

Code sample

Simply using the default template works:

import 'package:flutter/material.dart';

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

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(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // Here we take the value from the MyHomePage object that was created by
        // the App.build method, and use it to set our appbar title.
        title: Text(widget.title),
      ),
      body: Center(
        // Center is a layout widget. It takes a single child and positions it
        // in the middle of the parent.
        child: Column(
          // Column is also a layout widget. It takes a list of children and
          // arranges them vertically. By default, it sizes itself to fit its
          // children horizontally, and tries to be as tall as its parent.
          //
          // Invoke "debug painting" (press "p" in the console, choose the
          // "Toggle Debug Paint" action from the Flutter Inspector in Android
          // Studio, or the "Toggle Debug Paint" command in Visual Studio Code)
          // to see the wireframe for each widget.
          //
          // Column has various properties to control how it sizes itself and
          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

Logs

flutter run --verbose shows nothing unusual, and would make this exceed the maximum comment size.

@DeD1rk

Hi @DeD1rk, Thanks for filing the issue. I am not able to reproduce the crash. Could you please check if this happens with other IOS version?

I just tried on iOS 13.7 and 14.5 with flutter 2.8.1.

On 13.7 iPhone 11 it did not occur
On 14.5 iPhone 11 it did

Here's a recording and flutter --version:

crash_on_ios-14.5_flutter-2.8.1.mov

Flutter 2.8.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 77d935af4d (4 weeks ago) • 2021-12-16 08:37:33 -0800
Engine • revision 890a5fca2e
Tools • Dart 2.15.1

Sadly downloading other iOS versions takes a long time, so I haven't been able to find out for more versions yet. I'll try next with 14.0 and see if I can bisect at which iOS version I first get this. Finally, I just tried on macOS 12.0, this was no problem.

Possibly similar to: #95844
(Some similar reports also seem to be in the comments of #95568)
(Potentially also related: #96164)

Could you please check if this happens with other IOS version?

Just tried iOS 14.0 and 14.2, the problem occurred in both cases, so it looks like this happens (at least when I build) on Flutter >=2.8.0 with iOS >=14.0

Possibly similar to: #95844

Thanks, that does indeed look very similar. I saw that one before creating this issue, but was a bit confused as it sounded like that one was on 2.5.3, for which it does not occur here. Furthermore, those comments seem to indicate this being a relatively rare problem, but when I test this it happens 100% of the time.

we are having the same issue

this issue influence 2% of our users per day.

@DeD1rk

Thanks for the info, But I am unable to reproduce the crash on iPhone 11 (IOS 14.5) neither on stable 2.8.1,
nor on master 2.9, @DeD1rk does this issue reproduce on a physical device too?

I can reproduce this by enabling VoiceOver and then closing a Flutter app in the app switcher.

See #95844 (comment)

I see, indeed it seems I had some accessibility functions turned on without me knowing, and turning them off removes the problem. Strange that the simulators also use semantics for me though.
