tictactoe

A mobile game built in Flutter. You can find it published on stores:

• App Store (iOS)
• Play Store (Android)

This game was built using the game_template that you'll find in github.com/flutter/samples.

Note: The name of the game in app stores is "Tic Tac Toe Puzzle Game". Because that's what it is, and because every other variation of "Tic Tac Toe" is already taken.

Demo

To make it easier for everyone to play with the sample, it's currently published as a web demo, too, in two versions:

• a version mimicking a phone in portrait mode even when you open the link on a desktop
• a version that uses the whole browser window

Development

To run the app in debug mode:

flutter run

Code organization

Code is organized in a loose and shallow feature-first fashion. In lib/src, you'll therefore find directories such as ads, ai, audio or main_menu. Nothing fancy, but usable.

The state management approach is intentionally low-level. That way, it's easy to take this project and run with it, without having to learn new paradigms, or having to remember to run flutter pub run build_runner watch. You are, of course, encouraged to use whatever paradigm, helper package or code generation scheme to build on top of this project.

Building for production

The following assumes using FVM. Just remove fvm from the commands if you don't use FVM for Flutter version management.

To build and publish to github.io:

fvm flutter pub global run peanut \
--web-renderer canvaskit \
--extra-args "--base-href=/tictactoe/" \
&& git push origin --set-upstream gh-pages

To build the app for iOS (and open Xcode when finished):

fvm flutter build ipa --bundle-sksl-path warmup_2022-05-12_ios.sksl.json && open build/ios/archive/Runner.xcarchive

To build the app for Android (and open the folder with the bundle when finished):

fvm flutter build appbundle --bundle-sksl-path warmup_2024-01-30_android_pixel5.sksl.json && open build/app/outputs/bundle/release

SkSL shaders

To update the warmup_2022-04-27_xxx.sksl.json files used in the commands above, use the official SkSL shader warmup guide.

The game, despite being simple, uses shaders all over the place for the "drawing ink" effect. In my testing, the performance is fine on most reasonable devices, but why not make it even better?

Note: You can remove the --bundle-sksl-path warmup_xxx.json part of the commands above if you're in a place where you care more about development speed than performance. For example, when you need a quick turnaround for some testing and can't be bothered to manually re-capture the shaders.

Icon

Updating the launcher icon:

fvm flutter pub run flutter_launcher_icons
