Heads up... You've reached locked video content where the transcript will be shown as obfuscated text.

In this video, you will be displaying the Piece widget at a random position on the screen within the play area. To do this, first you will be generating a random position on the screen within the bounds of the play area and then render a Piece at the generated position.

draw() {
    if(positions.length == 0) {
        
    }
}
draw() {
    if(positions.length == 0) {
        positions.add(getRandomPositionWithinRange()); //add this
    }
}
getPieces() {
    List<Piece> pieces = [];
}
getPieces() {
    List<Piece> pieces = [];
    draw(); // Add this
}
getPieces() {
    List<Piece> pieces = [];
    draw();

    // Add this
    for(int i = 0; i < positions.length; i++) { 
        Piece p = Piece(
            posX: positions[i].dx.toInt(),
            posY: positions[i].dy.toInt(),
