Describe the bug

I get a black screen when resumed app some times

How to reproduce

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: IconButton(
          onPressed: () {
            CameraPicker.pickFromCamera(context);
          },
          icon: const Icon(Icons.camera),
        ),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

Steps to reproduce the behavior:

click the camera icon;
when the camera is on, lock screen;
unlock screen;
repeat step 2~3, util get a black screen;

Expected behavior

the camera is on after unlock screen;

And i had try the camera package's example, but unable to reproduce.

It is ok when remove following code in camera_picker_state.dart:

await Future.wait(
          <Future<void>>[
            newController
                .getExposureOffsetStepSize()
                .then((double value) => exposureStep = value)
                .catchError((_) => exposureStep),
            newController
                .getMaxExposureOffset()
                .then((double value) => maxAvailableExposureOffset = value)
                .catchError((_) => maxAvailableExposureOffset),
            newController
                .getMinExposureOffset()
                .then((double value) => minAvailableExposureOffset = value)
                .catchError((_) => minAvailableExposureOffset),
            newController
                .getMaxZoomLevel()
                .then((double value) => maxAvailableZoom = value)
                .catchError((_) => maxAvailableZoom),
            newController
                .getMinZoomLevel()
                .then((double value) => minAvailableZoom = value)
                .catchError((_) => minAvailableZoom),
            if (pickerConfig.lockCaptureOrientation != null)
              newController
                  .lockCaptureOrientation(pickerConfig.lockCaptureOrientation)
                  .catchError((_) {}),
            if (pickerConfig.preferredFlashMode != FlashMode.auto)
              newController
                  .setFlashMode(pickerConfig.preferredFlashMode)
                  .catchError((_) {
                validFlashModes[currentCamera]
                    ?.remove(pickerConfig.preferredFlashMode);

          ],
        );

Thanks for the feedback. I've found that controller methods will affect capture sessions occasionally in recent versions. I'll look into it next week.

Could you run git bisect to find out which commit produce the regression?

zhang873819 · 2023-10-08T01:41:04Z

Hi! There is some new tests:
It's good when use version(3.8.0)
It's good when use version(4.0.2) and use for set the config 'preferredFlashMode' to FlashMode.auto, use like

CameraPicker.pickFromCamera(
    context,
    pickerConfig:
       const CameraPickerConfig(preferredFlashMode: FlashMode.auto),
);

zhang873819 · 2023-10-08T01:49:44Z

And in version 3.8.0 the config property 'preferredFlashMode' default with FlashMode.auto.
It's also bad when use version 3.8.0 and set the config property 'preferredFlashMode' to FlashMode.off, use like

CameraPicker.pickFromCamera(
    context,
    pickerConfig:
       const CameraPickerConfig(preferredFlashMode: FlashMode.off),
);

zhang873819 · 2023-10-08T01:52:10Z

@AlexV525 So there is something wrong with the code that set flash mode:

if (pickerConfig.preferredFlashMode != FlashMode.auto)
              newController
                  .setFlashMode(pickerConfig.preferredFlashMode)
                  .catchError((_) {
                validFlashModes[currentCamera]
                    ?.remove(pickerConfig.preferredFlashMode);
              }),

AlexV525 · 2023-10-08T01:54:10Z

Could you try another device model for results?

zhang873819 · 2023-10-08T02:06:52Z

@AlexV525 There is the same with device redmi note 10. But it's lower frequency when use this device.

同样的问题在最新版本依旧出现，文件 camera_picker_state.dart await Future.wait，去除await 一切正常
可能：并发配置相机有几率没有回调成功
期望：是否配置超时时间

看上去好像是camer_android的一个bug。不太懂到底是为什么
