File _image; final picker = ImagePicker();

Future getImage() async {
  final pickedFile = await picker.getImage(source: ImageSource.camera);

  setState(() {
    if (pickedFile != null) {
      _image = File(pickedFile.path);
    } else {
      print('No image selected.');
    }
  });
}

Try this:

PickedFile pickedFile = await picker.getImage(source: ImageSource.camera);

if (pickedFile == null) {
  return null;
}

Directory appDirectory = await getApplicationDocumentsDirectory();
File newImage = File(appDirectory.path + 'fileName');
newImage.writeAsBytes(File(pickedFile.path).readAsBytesSync());

setState(() {
  _image = newImage;
  print(newImage.path + ' test');
});

                width: double.infinity,
                height: 300,
                color: Colors.grey[300],
                child: _image != null
                    ? Image.file(_image!, fit: BoxFit.cover)
                    : const Text('Please select an image'),
              )
            ]),
          ),
        ));
  }
}

Sometimes this error show up because you need to clean your build folder. Try to do flutter clean and rebuild again.
