[camera][iOS] app crashes with `Check failed: task_runners_.GetPlatformTaskRunner()->RunsTasksOnCurrentThread(). Process 521 stopped * thread #4, queue = 'io.flutter.camera.dispatchqueue'` when using startImageStream on master channel #94723

Unlike #44436, it crashes with any resolution preset.

Device is iPhone SE 2019, iOS 15.1

Code is nothing special, same as in example but after the initialisation I'm calling the startImageStream method.

The text was updated successfully, but these errors were encountered:

ljmatan · 2021-12-06T14:58:32Z

This would be my init method:

  Future<void> _initCameraServices() async {
    _deviceCameras = await availableCameras();
    _cameraController = CameraController(
      _deviceCameras!.firstWhere((e) => e.lensDirection == CameraLensDirection.back),
      Platform.isAndroid ? ResolutionPreset.max : ResolutionPreset.medium,
      enableAudio: false,
    );
    await _cameraController!.initialize();
    Future.delayed(
      const Duration(seconds: 2),
      () async => await _cameraController!.startImageStream(
        (image) {},
      ),
    );
  }

ljmatan · 2021-12-06T15:20:17Z

Obviously, this is another issue with just taking pictures manually #26960

ljmatan · 2021-12-06T15:27:40Z

So this would also be a blocker 🤔 #83856

ljmatan · 2021-12-07T08:18:49Z

Sorry, startImageStream does actually work properly on the stable Flutter version.

Hi @ljmatan, thanks for filing the issue.

What version of camera are you experiencing this issue with?

ljmatan · 2021-12-07T12:15:26Z

Hi @danagbemava-nc

Both 0.9.4+5 and 0.9.4+4

danagbemava-nc · 2021-12-07T13:37:48Z

Please provide the complete reproducible code sample as well.

However, to the best of my knowledge, the plugins are tested against the stable branch, so there's always the possibility that something like this could happen with a plugin.

ljmatan · 2021-12-07T14:04:50Z

Minimal code example:

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:camera/camera.dart';

List<CameraDescription> cameras;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  cameras = await availableCameras();
  runApp(CameraApp());
}

class CameraApp extends StatefulWidget {
  @override
  _CameraAppState createState() => _CameraAppState();
}

class _CameraAppState extends State<CameraApp> {
  CameraController controller;

  @override
  void initState() {
    super.initState();
    controller = CameraController(cameras[0], ResolutionPreset.max);
    controller.initialize().then((_) {
      if (!mounted) {
        return;
      }
      setState(() {});
      controller.startImageStream((_) {});
    });
  }

  @override
  void dispose() {
    controller?.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    if (!controller.value.isInitialized) {
      return Container();
    }
    return MaterialApp(
      home: CameraPreview(controller),
    );
  }
}

danagbemava-nc · 2021-12-07T15:20:43Z

Crash can be reproduced on master with sample below. stable works just fine.

updated sample

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:camera/camera.dart';

List<CameraDescription>? cameras;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  cameras = await availableCameras();
  runApp(CameraApp());
}

class CameraApp extends StatefulWidget {
  @override
  _CameraAppState createState() => _CameraAppState();
}

class _CameraAppState extends State<CameraApp> {
  late CameraController controller;

  @override
  void initState() {
    super.initState();
    controller = CameraController(cameras![0], ResolutionPreset.max);
    controller.initialize().then((_) {
      if (!mounted) {
        return;
      }
      setState(() {});
      controller.startImageStream((_) {});
    });
  }

  @override
  void dispose() {
    controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    if (!controller.value.isInitialized) {
      return Container();
    }
    return MaterialApp(
      home: CameraPreview(controller),
    );
  }
}

I did some initial investigation. It turned out to be a threading issue. For now I plan to just fix this issue and stop the crash. It may worth our efforts to refactor it in the future, as some code is getting a bit complicated to maintain.

@hellohuanlin Before you get too deep into this issue, check out #52578, flutter/plugins#4007, flutter/plugins#4140,

hellohuanlin · 2021-12-10T19:34:30Z

@jmagman This is helpful. Thank you!

I'm having this issue in stable 2.10.1 the moment I call startImageStream.

@acoutts looks like you are on an old version of the plugin. We had multiple improvements since then. could you try the latest version?

acoutts · 2022-02-24T20:13:36Z

Thanks- indeed it's fixed on the latest one. I'm just now patching the android 12 capture bug that prevents captures on the Pixel 6 and will file a separate PR for that.
