List.add not adding element to a boolean list in flutter

I have two Lists, imageFileList and values

// contains a list of image files which are captured from the camera page
    List<File> imageFileList = widget.imageFileList;
    // Values list is filled with boolean values which are defaulted to false and contains the same length as imageFileList
    List<bool> values = widget.values;

the imageFileList gets a new File added when user selects a picture from the gallery, and i want to simultaneously add another bool entry to the values List, as such –

    Future pickImage() async {
      try {
        final image =
            await ImagePicker().pickImage(source: ImageSource.gallery);
        if (image == null) return;
        final imageTemp = File(image.path);

        setState(() {
// adding a new image to imageFileList
          imageFileList.add(imageTemp);
// adding a new bool to values List
          values.add(false);
        });

        // rebuildAllChildren(context);
      } catch (e) {
        print(e);
      }
    }

When i use pickImage(), the file gets added to the imageFileList, but the false bool is not getting added to the values List.

debug output shows this line when i print the lengths of imageFileList and values List –

              print("imagelist = " +
                      imageFileList.length.toString());
                  print("values = " +
                      values.length.toString());

// debug output
I/flutter (20710): imagelist = 5
I/flutter (20710): values = 4

any suggestions on what might be wrong?

here is the full code –

  Widget build(BuildContext context) {
    // contains a list of image files which are captured from the camera page
    List<File> imageFileList = widget.imageFileList;
    // Values list is filled with boolean values which are defaulted to false and contains the same length as imageFileList
    List<bool> values = widget.values;

    Future pickImage() async {
      try {
        final image =
            await ImagePicker().pickImage(source: ImageSource.gallery);
        if (image == null) return;
        final imageTemp = File(image.path);

        setState(() {
          imageFileList.add(imageTemp);
          values.add(false);
        });

        // rebuildAllChildren(context);
      } catch (e) {
        print(e);
      }
    }

    getStoragePermissionStatus() async {
      await Permission.camera.request();
      var status = await Permission.storage.status;
      if (status.isGranted) {
        log('Camera Permission: GRANTED');
        setState(() {
          _isStoragePermissionGranted = true;
        });

        // asking the user to select an image IF they grant storage permission
        await pickImage();
        print(_isStoragePermissionGranted);
      } else {
        log('Camera Permission: DENIED');
      }
    }

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

I have tried to with the setState and without it, however both times, only the imageFileList gets the new entry added.

I need to add a new entry to values List when the imageFileList gets a new entry added to it.
