Innovating Web Development with the First Flutter Web App

Project Overview

The New York Times puzzles are wildly popular with millions of players every day. But developing new games and maintaining existing ones was a huge undertaking given the complexity of web, mobile, and desktop platforms. Very Good Ventures collaborated with the Times and Google to explore Flutter on the Web as a viable alternative — creating the first commercial Flutter Web prototype that debuted at Google IO 2019.

New York Times KENKEN puzzle app made its debut on stage at Google I/O 2019.

First Commercial Flutter Web App

Flutter is well-known as the best solution for mobile apps, but Flutter on the Web is a game-changer. The KENKEN app designed and developed by VGV debuted in the technical keynote of Google I/O 2019 demonstrating the power of Flutter on the Web.

Flutter on All Platforms

Using responsive design patterns and device specific customizations, VGV successfully demonstrated how a single codebase can create beautiful high performance apps for iOS, Android, mac, Windows, and the Web!

I/O Photo Booth was featured in four tents in the interactive I/O Adventure and users could access the web app from these locations.

Incredible Productivity

VGV implemented continuous integration that published app updates to a Firebase hosting project, which drastically sped up design review and client feedback. Rather than building apps and running mobile app betas, the team could iterate in near real-time thanks to Flutter on the Web.

"Rather than re-writing the puzzle app for every different platform, they can just write it once with Flutter."
