Building Games with Flutter

By: Paul Teale

Overview of this book

With its powerful tools and quick implementation capabilities, Flutter provides a new way to build scalable cross-platform apps. In this book, you'll learn how to build on your knowledge and use Flutter as the foundation for creating games. This game development book takes a hands-on approach to building a complete game from scratch. You'll see how to get started with the Flame library and build a simple animated example to test Flame. You'll then discover how to organize and load images and audio in your Flutter game. As you advance, you'll gain insights into the game loop and set it up for fast and efficient processing. The book also guides you in using Tiled to create maps, add sprites to the maps that the player can interact with, and see how to use tilemap collision to create paths for a player to walk on. Finally, you'll learn how to make enemies more intelligent with artificial intelligence (AI). By the end of the book, you'll have gained the confidence to build fun multiplatform games with Flutter.

Animating with particles

In this section, we will show you how to create great particle effects and animate them. First, we will create a new file for storing our effects in the utils folder, which we can use from anywhere:

  1. In the utils folder, create a new file called effects.dart and open the file.
  2. Add the following code for creating the exploding particle:
    Particle explodingParticle(Vector2 origin, 
      MaterialColor color) {
      double distanceToMove = 15.0;
      return Particle.generate(
        lifespan: 0.8,
        count: 12,
        generator: (i) {
          double angle = i * 30;
          double xx = 
            origin.x  + (distanceToMove * cos(angle));
          double yy = 
            origin.x  + (distanceToMove * sin...
