I had the same problem and i check the state of memory, and yes, this case happen beacuse the memory Ram of the device is full and close the task automaticly, so .

I check the state memory in the observatory of flutter, you press "Ctrl + Shift + P" when the aplication is running and write observatory for see the state of memory of the device enter image description here enter image description here
I defined the cacheHeight and cacheWidth with the atribbute of Image.file widget and i modified the filterQuality atributte in none:

Image.file( File(path), filterQuality: FilterQuality.none, cacheHeight: 66, cacheWidth: 50, )

Excuseme for my english.

Run your code on another device then it can work properly. The first time I used 'Xiaomi Note 7 pro' but shows the same error after run the code on another device its work properly. Also, you can update the version of your image_picker.

It's worked for me and I used:

image_picker: ^0.8.4+1

Flutter version: 2.2.3

 void _pickImageCamera() async {
final picker = ImagePicker();
final pickedImage =
await picker.pickImage(source: ImageSource.camera, imageQuality: 90);
final pickedImageFile = File(pickedImage!.path);
setState(() {
  _pickedImage = pickedImageFile;
});
Navigator.pop(context); }

Try below code hope its helpful to you. In below code I used picked image using Camera as well as Gallery

Declare File type form dart.io package

File? imagePicked;

Create Function for pick up the image from Gallery

void gallaryImage() async {
    final picker = ImagePicker();
    final pickedImage = await picker.pickImage(
      source: ImageSource.gallery,
    );
    final pickedImageFile = File(pickedImage!.path);
    setState(() {
      imagePicked = pickedImageFile;
    });
  }

Create Function for pick up the image from Camera

void cameraImage() async {
    final picker = ImagePicker();
    final pickedImage = await picker.pickImage(
      source: ImageSource.camera,
    );
    final pickedImageFile = File(pickedImage!.path);
    setState(() {
      imagePicked = pickedImageFile;
    });
  }

Create your Widget

 Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        TextButton.icon(
          onPressed: cameraImage,
          label: Text(
            'Camera',
            style: TextStyle(
              color: Colors.black,
            ),
          ),
          icon: Icon(
            Icons.camera,
          ),
        ),
        TextButton.icon(
          onPressed: gallaryImage,
          label: Text(
            'Gallery',
            style: TextStyle(
              color: Colors.black,
            ),
          ),
          icon: Icon(Icons.image),
        ),
      ],
    ),

If you are using an iOS device then you have to add permission for image picking. Add these line in your info.plist file.

<key>NSCameraUsageDescription</key>
<string>Access to take a photo by camera</string>
<key>NSAppleMusicUsageDescription</key>
<string>Access to pick a photo</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Access to pick a photo</string>
