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.
