Flame is a modular Flutter game engine that provides a complete set of solutions for games. Provides you with a simple implementation of the game cycle and the necessary functions that you may need in the game, like input, images, sprites, animation, collision detection, and a component system, which is called Flame Component System (abbreviated FCS).
