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
],
),
),
);
}
