I am also facing same issue while taking image from image_picker source: camera.
It crashed my app if i used frequently.

Here is the scenario,
I clicked image and save it and image saved.
but if i do same for 2-3 times than my app crashed.

Here, is my code

Future<bool> saveTimeInOut(MarkTime mk) async {
  try{
    File imagei = null;
    imagei = await ImagePicker.pickImage(source: ImageSource.camera);
    if(imagei!=null) {      
    final tempDir = await getTemporaryDirectory();
    
    String path = tempDir.path;
    int rand = new Math.Random().nextInt(10000);
    
    im.Image image1 = im.decodeImage(imagei.readAsBytesSync());
    imagei.deleteSync();
   
    im.Image smallerImage = im.copyResize(image1, 500); // choose the size here, it will maintain aspect ratio
   
    
    File compressedImage = new File('$path/img_$rand.jpg')..writeAsBytesSync(im.encodeJpg(smallerImage, quality: 50));
    

    
    Dio dio = new Dio();
    FormData formData = new FormData.from({
    "uid": mk.uid,
    "location": mk.location,
    "aid": mk.aid,
    "act": mk.act,
    "shiftid": mk.shiftid,
    "refid": mk.refid,
    "latit": mk.latit,
    "longi": mk.longi,
    "file": new UploadFileInfo(compressedImage, "image.png"),
    });
    print("5");
    Response<String> response1=await dio.post("https://sandbox.ubiattendance.com/index.php/services/saveImage",data:formData);
    //Response<String> response1=await dio.post("http://192.168.0.200/ubiattendance/index.php/services/saveImage",data:formData);
    //Response<String> response1 = await dio.post("https://ubitech.ubihrm.com/services/saveImage", data: formData);
    
    compressedImage.deleteSync();

    Map MarkAttMap = json.decode(response1.data);
    print(MarkAttMap["status"].toString());
    if (MarkAttMap["status"] == 1 || MarkAttMap["status"] == 2)
      return true;
    else
      return false;
    }else{
      print("6");
      return false;
    }
  } catch (e) {
    print(e.toString());
    return false;
  }
}

Where do the forward slashes in below command come from?
It's quite some time I used Windows and don't know how it deals with slashes in paths.

flutter build bundle --suppress-analytics --target C:\Users\UBIAPP\AndroidStudioProjects\NewAttFlutter\lib\main.dart --target-platform android-arm64 --depfile C:\Users\UBIAPP\AndroidStudioProjects\NewAttFlutter\build\app\intermediates\flutter\debug/snapshot_blob.bin.d --asset-dir C:\Users\UBIAPP\AndroidStudioProjects\NewAttFlutter\build\app\intermediates\flutter\debug/flutter_assets --debug

NewAttFlutter\build\app\intermediates\flutter\debug/flutter_assets' (OS Error: Access is denied.
, errno = 5)

probably caused by some antivirus tools or other task that kept the file open and prevented the directory to be deleted and recreated.

Try excluding the directory in Antivirus and if it doesn't help restart your computer.

I have the same problem, when I open the camera after 2 seconds the application crashes without any warning or error, not logging anything.

[cameronalicia]

@Errichamonda I'm facing the same issue, my app crashes immediately without warning or any error. Did you ever find a solution?

@cameronalicia
Can you make a minimal demo project which can help reproduce your issue?

[cameronalicia]

I figured out that it was a result of a previous package I had used at some point, and when I removed the code required for that package from my AndroidManifest.xml, everything works fine again. So it was not a problem related to this package after all, I apologize.
