How we built it
I/O FLIP is an example of a seamless integration between Google’s new AI tools and tools you already know and love. Character images are generated with DreamBooth on Muse, and descriptions were generated using the PaLM API. The game UI, and animations are created in Flutter and the backend is written in Dart. It uses a suite of Firebase and Google Cloud tools for hosting and sharing.Learn more

What is this?
I/O FLIP is an AI-designed card game powered by Google, built for Google I/O 2023.
How were the images and descriptions created?
Images were generated using Muse, a text-to-image Transformer model developed by Google Research, and trained using artwork we created. The text was generated using the PaLM API based on text inputs created by Google. To ensure a positive experience for all users, images and text were generated offline so that they could be vetted by human reviewers to ensure they adhere to Google AI Principles.
How was AI used?
AI was used to create the images and descriptions on each card.
Are there prizes for the winners?
There are no prizes as part of the game.
What data is stored and publicly available when sharing?
If you choose to share, your initials, cards and score will be made available at a unique URL for 30 days and then automatically deleted.

Creating home and lock screen widgets for your Flutter app
In this workshop, we'll walk through the steps needed to add Home Screen widgets and Lock Screen widgets to your Flutter app in iOS and Android.
Before you arrive
This workshop will walk through both native Android and native iOS development. In addition to having the Flutter SDK installed and a development environment, you’ll need certain software to follow each portion. To follow along with the Android portion, you’ll only need Android Studio. To follow along with the iOS portion, you’ll need a MacOS computer with Xcode installed, and an Apple Developer account. More information can be found in this Github repository’s README.
Hands-on with multi-factor authentication and Firestore count queries
Get the latest Firebase features for your Flutter app. We'll start with a basic app, and then add multi-factor phone authentication to ensure more secure sign-in.Then we'll use the new COUNT() operator in Firestore to include counts in the app at just a fraction of the cost and complexity.
Before you arrive
In order to follow along with this workshop, you’ll need a Flutter and Firebase development environment set up. You can follow the setup instructions at the Get to know Firebase for Flutter codelab. It is important that you complete step one through four of the codelab, to have your environment set up. If you have no Firebase experience, you are encouraged to complete the entire codelab before the workshop.
How to build the Basil Material 3 study
Learn how to use advanced theming features and the Material hct color system with the Basil Material 3 study. The Basil app also showcases how to build for ambient and smart displays.
Before you arrive
This workshop includes steps of the design process, which will help developers learn how to turn design into code. In order to follow along with the design process portion of the workshop, you should install Figma, or plan on using the Web Client for Figma. (If you plan on using the web client, you should test Figma beforehand, as it’s less reliable than the desktop client if the internet connection isn’t fast enough.) Other than Figma, this workshop will only use the standard Flutter development environment.
