Casual Games Toolkit

The Flutter Casual Games Toolkit pulls together new and existing resources so you can accelerate development of games on mobile platforms.

This page outlines where you can find these available resources.

The Flutter framework can create performant apps for six target platforms from the desktop to mobile devices to the web.

With Flutter’s benefits of cross-platform development, performance, and open source licensing, it makes a great choice for games.

Casual games fall into two categories: turn-based games and real-time games. You might be familiar with both types of games, though perhaps you didn’t think about them in quite this way.

Turn-based games cover games meant for a mass market with simple rules and gameplay. This includes board games, card games, puzzles, and strategy games. These games respond to simple user input, like tapping on a card or entering a number or letter. These games are well suited for Flutter.

Real-time games cover games a series of actions require real time responses. These include endless runner games, racing games, and so on. You might want to create a game with advanced features like collision detection, camera views, game loops, and the like. These types of games could use an open source game engine like the Flame game engine built using Flutter.

The Casual Games Toolkit provides the following free resources.

A repository that includes three new game templates that provide a starting point for building a casual game.

A base game template that includes the basics for:

A card game template that includes everything in the base template plus:

An endless runner template created in partnership with the open source game engine, Flame. It implements:

A sample game built on top of the endless runner template, called SuperDash. You can play the game on iOS, Android, or web, view the open source code repo, or read how the game was created in 6 weeks.

The included game templates and cookbook recipes make certain choices to accelerate development. They include specific packages, like provider, google_mobile_ads, in_app_purchase, audioplayers, crashlytics, and games_services. If you prefer other packages, you can change the code to use them.

The Flutter team understands that monetization might be a future consideration. Cookbook recipes for advertising and in-app purchases have been added.

As explained on the Games page, you can leverage up to $900 in offers when you integrate Google services, such as Cloud, Firebase, and Ads, into your game.

error 重点提醒： Terms and conditions apply. You must connect your Firebase and GCP accounts to use credits for Firebase services and verify your business email during sign up to earn an additional $100 on top of the normal $300 credit. For the Ads offer, check your region’s eligibility.

For Google I/O 2022, both the Flutter team and Very Good Ventures created new games.

VGV created the I/O Pinball game using the Flame engine. To learn about this game, check out I/O Pinball Powered by Flutter and Firebase on Medium and play the game in your browser.

The Flutter team created I/O Flip, a virtual CCG. To learn more about I/O Flip, check out How It’s Made: I/O FLIP adds a twist to a classic card game with generative AI on the Google Developers blog and play the game in your browser.
