Welcome to our recap of everything Flutter and Dart at Google Cloud Next 2026. Below we answer the most pressing questions about the major announcements, hands-on experiences, and key sessions from the event. Jump to a specific topic:

• Big announcements for Dart and Firebase
• The GenLatte experience
• Agentic mobile and web demos
• The Builder Hub
• Developer keynote highlights
• Toyota and Talabat enterprise success stories
• Generative UI deep dive
• Building full-stack Dart session

What major announcements were made regarding Dart and Firebase?

The team announced a preview of Dart support for Firebase Functions, enabling full-stack Dart development. This means you can now use Dart for both the frontend and backend, streamlining your codebase. Deeper integrations with Firebase were also introduced through the Dart Admin SDK, reducing context switching and accelerating development. Check out the announcement blog and documentation for details, and stay tuned for a full breakout session at Google I/O.

What was the GenLatte experience at the conference?

Google set up an AI-powered specialty coffee shop called GenLatte in the center of Next. It was built entirely with Flutter GenUI. Attendees ordered drinks using a GenUI Flutter app, then watched baristas craft a latte and print a custom image on the foam—generated by Nanobanana AI. It was a delightful demonstration of how Flutter can power interactive, real-world experiences.

What demos were showcased on the expo floor?

The expo floor buzzed with energy. Three major Dart and Flutter demos were featured: Fullstack Dart (integrating Firebase Functions), GenUI (generating UI on the fly), and a special appearance by the VGV team. Attendees also saw the Partiful app, where the entire UI is generated dynamically, showcasing the power of generative UIs.

What was the Builder Hub?

The Builder Hub served as the home base for developers on the Expo floor. It featured dedicated booths for Flutter, Firebase, and Go, providing a space for attendees to connect with experts, ask questions, and explore new tools. It was a vibrant community hub where developers could meet, greet, and share ideas.

Who delivered the developer keynote and what was the theme?

Emma Twersky hosted the Developer Keynote, highlighting how Flutter aligns with Google Cloud's big bet on the future of agents. Richard Seroter joined on stage to underscore the strategic importance of agent-based architectures. The keynote set the stage for many of the subsequent sessions and announcements about full-stack development.

How are Toyota and Talabat using Flutter for enterprise success?

Abdallah Shaban hosted a session featuring Toyota and Talabat. Toyota demonstrated how Flutter revolutionizes automotive UX in their next-generation infotainment systems. Talabat showcased how Flutter helps them innovate faster and scale across the Middle East. These real-world enterprise stories underlined Flutter’s ability to transform core products at scale.

What did the Generative UI deep dive cover?

Led by Yegor Jbanov and Andrew Brogdon, this session explored moving beyond text-based chatbots. Instead, agents can create their own UIs dynamically using Flutter GenUI. The session provided practical guidance on giving agents the power to build interfaces on the fly. The recording will be available worldwide on the Flutter YouTube channel after Google I/O.

What was covered in the 'Building full-stack Dart' session?

Rody Davis and Kevin Moore shared why developers should be excited about full-stack Dart. They explained how Dart support for Firebase Functions enables seamless front-to-back development, reducing the need to switch languages and tools. The session included live coding and best practices for building complete applications in Dart.
