We have the game-over dialog but the score it shows is always 0. In this episode, you will be implementing the scoring feature in the game.

Widget getScore() {
    return Positioned(
        top: 50.0,
        right: 40.0,
        child: Text(
            "Score: " + score.toString(),
            style: TextStyle(fontSize: 24.0),
        ),
    );
}

if (foodPosition == positions[0]) {
      length++;
      speed = speed + 0.25;

      // Add this
      score = score + 5;
      ...
}

void restart() {
    // Add this
    score = 0;
    ...
}

@override
  Widget build(BuildContext context) {
    ...

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