For the camera example, I would rather do:

    Camera camera = createCamera({"rotation": 90});

If you need another camera with different parameters then create a new one. You can build the options before the creating the cameras to avoid duplication.

    Bitmap bitmap = createBitmap({data: data, samepleSize: 4});
    ImageView imageView = createImageView(bitmap);

In the case where you are mutating image view, it's an optimization to reuse the same memory that could be handled by your language/framework so you don't have to think about it. For example, like with react it could create an internal representation of what is rendered and then diff it with the new rendering and reuse the internal representation of image view and mutate it for you so you don't have to think about doing the optimization yourself.
