I am getting this error after approving the camera permission

thread #43, queue = 'ProviderImageSurfaceCacheQueue', stop reason = EXC_BAD_ACCESS (code=1, address=0x127b00000)
frame #0: 0x000000022c20310c libsystem_platform.dylib_platform_memmove + 188 libsystem_platform.dylib:

here is my code example

return Scaffold(
body: SafeArea(
child: Stack(
children: [
ScanKitWidget(
controller: _controller,
continuouslyScan: true,
boundingBox: rect, ),
Align(
alignment: Alignment.topCenter,
child: GlassContainer.clearGlass(
blur: 8,
borderColor: Colors.transparent,
margin: EdgeInsets.only(top: 60.h),
elevation: 2,
shape: BoxShape.rectangle,
borderRadius: BorderRadius.circular(5),
color: Colors.white12,
height: 50.h,
width: 150.w,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
IconButton(
onPressed: () {
_controller.switchLight();
},
icon: const Icon(
Icons.lightbulb_outline_rounded,
color: Colors.white,
size: 25,
)),
SizedBox(
width: 0.075.sw,
),
IconButton(
onPressed: () async {
_controller.pickPhoto();
},
icon: Image.asset(
'assets/images/photo.png',
width: 25,
height: 25,
color: Colors.white,
),
)
],
),
),
),
Align(
alignment: Alignment.center,
child: CustomPaint(
painter: QrScanBoxPainter(
boxLineColor: Colors.cyanAccent,
animationValue: _animationController?.value ?? 0,
isForward:
_animationController?.status == AnimationStatus.forward,
),
child: SizedBox(
width: qrScanSize,
height: qrScanSize,
),
),
),

                  ],
                )),
          ),
      ],
    ),
  ),
);

I even tested the example project then clicked on customized view and also crashed

If you are using the flutter_easy_permission plugin to request permissions, then you may want to try using a different Flutter plugin, as flutter_easy_permission is not actively maintained and may have compatibility issues on higher versions of iOS.

using

no I am not using this library, i run your example project and still getting the same error

What I mean is that I am using the flutter_easy_permission plugin in my example project. I can't reproduce the issue with my iOS device here, perhaps you can provide, for reference, the model number of the device reporting the error, the system version, and the Flutter SDK version. I think this issue is most likely caused by not successfully obtaining access to the camera, and you should call ScanKit after obtaining authorization.
