You have the Snake moving around the screen. In this episode, you are going to render food on the screen. We will render this food at a random position within the bounds of the play-area on the screen. Later we will write the code to make the Snake be able to eat the food and grow in length.

void drawFood() {
    if (foodPosition == null) {
        foodPosition = getRandomPositionWithinRange();
    }
}
void drawFood() {
    ...

    // Add this
    food = Piece(
        posX: foodPosition.dx.toInt(),
        posY: foodPosition.dy.toInt(),
        size: step,
        color: Color(0XFF8EA604),
        isAnimated: true,
    );
}
List<Piece> getPieces() {
    ...
    draw();
    drawFood(); // Add this

    ...

    return pieces;
}
@override
  Widget build(BuildContext context) {
    ...

    return Scaffold(
        body: Container(
            color: Color(0XFFF5BB00),
            child: Stack(
                children: [
                    ...getPieces(), 
                    getControls(), 
                    food, // Add this
                ],
            ),
        ),
    );
}
