Google I/O 2021 Photo Booth built with Flutter and Firebase
Google I/O 2021 Photo Booth built with Flutter and Firebase. A Photo Booth built with Flutter and Firebase for Google I/O 2021. We (the folks at Very Good Ventures) teamed up with Google to bring an interactive experience to this year’s Google I/O: a photo booth! You can take pictures with well-known Google mascots: Flutter’s Dash, Android Jetpack, Chrome’s Dino, and Firebase’s Sparky, and decorate photos with stickers, including party hats, pizza, funky glasses, and more. Finally, you can share photos on social media and download them to update your profile picture for the event! We built the I/O Photo Booth using Flutter on the web and Firebase. Because Flutter now offers support for web apps, we thought it would be a great way to make this app easily accessible to attendees all over the world for this year’s virtual Google I/O. Flutter’s web support eliminates the barrier of having to install an app from an app store and also gives you the flexibility to run it on your device.
