Edit this Flutter pong game

Get a small taste of what it's like to develop games in Flutter with this quick tutorial and challenge

Step 1: Run the game

Click run and try to complete the game, getting a sense for how it works.

Step 2: Change the background color

The game's current background color is red. The code below changes the background color to blue. Change it to a color of your choice.

                    
                      @override
                      Color backgroundColor() => Colors.blue;

Step 3: Make the ball move faster

Now this game is all about making the ball move fast. See if you can make the ball move a bit faster by making the following change:

                    
                      static const double startingBallSpeed = 2.5;

Step 4: Change element sizes!

Based on the last two steps, can you figure out how to change the size of the ball and/or the width of the paddles? (Hint: the image shows you where you might look!)

Challenge #1 Aspect Ratios and Responsiveness

The game is currently only balanced in a specific aspect ratio. Can you decide on a different aspect ratio and embed the game in the maximum amount of space that aspect ratio can take up within the actual available space?

Challenge #2 Angles & Physics

In real Pong, the ball bounces at different angles off the paddle, depending on where it strikes the paddle. In this Pong game, it does not (it always bounces at a 45° angle).

Can you implement a bounce algorithm closer to the original Pong's actual algorithm?

(Hint: In Pong, the ball does not bounce according to the normal laws of physics. Instead, if the ball hits the exact center of the paddle, it will bounce straight out, regardless of its incoming angle. Otherwise, the higher up the ball collides with the paddle, the steeper the angle of its upward bounce. Likewise, the lower down the ball collides with the paddle, the steeper the angle of its downward bounce)
