Building Games with Flutter

Updated code of the book "Building Games with Flutter" by Paul Teale / Packt

updated for Flame 1.22 / Flutter 3.27. NOTE the code now diverges from the book but works with these versions and it is run through flutter_lints.

• https://flame-engine.org/
• https://flutter.dev/

Rationale: I found the book to be a good comprehensive introduction to game development with the Flame game engine. However, Flame has changed a lot since the book came out. So I updated the code as I went through the chapters as an exercise. I left most of the original code intect, with three notable differences:

1. Throughout, I use the camera system, adding components to the world and user interface (HUD) elements to camera.viewport instead of adding everything to the game object. See https://docs.flame-engine.org/latest/flame/camera_component.html
2. Also I tweaked the particle effect (chapter 9) a bit.
3. I added the flutter_lints package and some analyzer options for better code insights, then refactored the code following the linter recommendations

I checked

• chapter 1, 2, 4 on macOS (chapter 3 doesn't have code),
• chapter 5 to 7 and 9 to 11 on macOS and on an Pixel 7 / Android 35 emulator, and
• chapter 8 on Chrome / web.

Platform folders are not in git so you have to add them yourself.

TODO: test on mobile devices, refactor a few more places, tweak parameters
