This is a game of Rubik's cube written in Flutter and yes, It's 3D !

I am a Flutter fan and I just learned to play Rubik's cube. Then I wonder if I can write an app about it in Hack20.

Flutter has a great graphics library but unluckily it only support 2D. I use some matrix transform to simulate the camera change in 3D, and manually calculate the depth of every surface of cube.

Here is a video to show how it looks like.
