Describe the bug
华为手机，频繁进入/退出拍照界面可能会黑屏

How to reproduce

任意一个flutter app，频繁进入退出，即有概率复现

Steps to reproduce the behavior:
1、点击拍照按钮
2、退出拍照界面
3、重复1、2步骤

Expected behavior

正常打开摄像头

Version information

  • Device: [HUAWEI Mate 30E Pro 5G]
  • OS: [HarmonyOS 2.0.0]
  • Package Version: [4.3.1]
  • Flutter Version:
  • Flutter 3.24.0 • channel stable • https://github.com/flutter/flutter.git Framework • revision 80c2e84975 (3 months ago) • 2024-07-30 23:06:49 +0700 Engine • revision b8800d88be Tools • Dart 3.5.0 • DevTools 2.37.2

Additional context

  1. 通过跟踪发现，下面这个文件的第485行-498行之间的这段future有可能会阻塞整个future[]的执行，从而导致整个页面黑屏

flutter_wechat_camera_picker/lib/src/states/camera_picker_state.dart

Line 485 in 384609c

if (description.lensDirection != CameraLensDirection.front &&

  1. 因为当出现黑屏的时候，第503行的debug日志，不会打印出来。正常情况下，503行的日志可以打印出来。

  2. 实测删除485-498行，黑屏就不会出现了。只不过不能设置闪光灯的初始设置了。

  3. camera官方的demo是不会出现黑屏问题的。
