Chapter 19 — Flutter crash course for game development

Level: beginner in Flutter, intermediate in Dart Estimated time: 8 h Prerequisites: chapters 01 to 18 (complete console Dart: OOP ch. 08 to 11, null safety ch. 12, exceptions ch. 13, asynchronous programming ch. 15, project organization ch. 16) What you will be able to do by the end: install the Flutter SDK, create a project, understand a widget tree, manage state with setState(), draw on a Canvas with CustomPainter, and animate a square on screen with a Ticker, in pure Flutter, with no game engine at all.

Verified version: Flutter 3.44 (stable channel). Verification date: August 8, 2026, against https://docs.flutter.dev/get-started/install, https://docs.flutter.dev/install/manual, https://docs.flutter.dev/release/release-notes and https://api.flutter.dev. Flutter evolves quickly. If your flutter --version shows a higher number, that is not a problem: everything taught in this chapter is part of Flutter's stable core and has not changed in years.
