Earlier this year, the Flutter team released GenUI: an SDK that enables AI to compose UIs based on your design system at runtime.

To help Google present it at Google I/O and Google Cloud Next, gskinner was challenged to conceptualize, design, and build Hatcha: an open-source event-planning app for iOS, Android and the web, where a host plans an event through a conversational interview with AI, and GenUI generates dynamic, themed, and interactive invites. As guests respond, the planning experience dynamically composes itself around the specific context gathered for that particular event.

It’s not a form you fill out and forget — it’s a dynamic, evolving experience that GenUI actively constructs around the people involved.

Over the past few months, we’ve been building Hatcha: an open-source, cross-platform, event-planning app experience written for Android, iOS, and the Web. We’ve been excited to see this project shared on the big stage as a feature in the Flutter keynote at Google I/O with an in-depth demo at Google Cloud Next.

Earlier this year we joined forces with the FlutterFlow team to produce a set of “Vignettes” to showcase the power and customization possible inside of FlutterFlow. Recently we deployed them to the FlutterFlow Marketplace so that everyone can dive in and see the techniques that made these components possible!
