Breaking: At Google Cloud Next 2026 in Las Vegas, the Flutter and Dart team has unveiled a preview of Dart support for Firebase Functions, marking a leap toward full-stack development with a single language. The announcement, made before over 30,000 attendees, positions Flutter as a cornerstone of Google Cloud's agentic future.
"This is a game-changer for developers," said Emma Twersky, developer keynote host. "Now you can write both frontend and backend in Dart, dramatically reducing context switching and accelerating delivery."
Key Announcements
The preview of Dart support for Firebase Functions allows developers to use Dart for cloud functions alongside the Dart Admin SDK. This integration deepens the Firebase ecosystem, enabling more seamless workflows. Learn more about full-stack Dart below.
In addition, the team introduced GenLatte, an AI-powered coffee shop built entirely with Flutter GenUI. Attendees used a GenUI Flutter app to order custom lattes with AI-generated foam art, showcasing the framework's generative UI capabilities.
"GenLatte wasn't just a demo—it was a living example of what's possible when you combine Flutter, GenUI, and cloud AI," said Kate Lovett, Flutter engineer, as she helped the Dash mascot enjoy a latte.
Onsite Experiences and Demos
The expo floor featured three major Dart and Flutter demos, including Full-stack Dart, GenUI, and a special appearance by Very Good Ventures (VGV). The Partiful app demonstrated dynamically generated UIs on the fly.
The Builder Hub served as a developer home base, with dedicated booths for Flutter, Firebase, and Go, allowing attendees to connect with experts and explore new tools.
Enterprise Success Stories
Toyota shared how Flutter powers their next-generation infotainment systems, revolutionizing automotive UX. Talabat showcased how the framework helps them innovate faster and scale across the Middle East. Abdallah Shaban led the customer story session, highlighting real-world enterprise adoption.
"Flutter is transforming core products at scale," said Rody Davis, Flutter product manager. "Toyota and Talabat are proof that this framework is enterprise-ready."
Full-Stack Dart Deep Dive
In a dedicated session, Rody Davis and Kevin Moore explained why developers should be excited about today's announcements. They demonstrated how full-stack Dart reduces the need for multiple languages and platforms, enabling faster iterations.
"You can now own your entire stack with Dart, from UI to database triggers," said Kevin Moore. "This is the productivity boost the community has been waiting for."
Generative UI: Beyond Chatbots
Yegor Jbanov and Andrew Brogdon led a session on moving beyond text-based chatbots by giving agents the power to create their own UI. The session, which will be available on the Flutter YouTube channel after Google I/O, demonstrated how GenUI can dynamically assemble interfaces tailored to user intent.
"This is a new paradigm for agentic experiences," said Andrew Brogdon. "We're enabling UIs that adapt in real time to what the user wants to achieve."
Background
Google Cloud Next is Google's flagship cloud conference, attracting thousands of developers, partners, and enterprises worldwide. The Flutter and Dart team has used the event for major announcements, including the 2026 showcase of full-stack Dart and GenUI innovations. The developer keynote, hosted by Emma Twersky, emphasized Flutter's role in Google Cloud's strategic bet on agent-based computing.
What This Means
For developers, Dart support for Firebase Functions unlocks a streamlined workflow where frontend and backend logic share the same language and tooling. The GenUI demos signal a shift from static interfaces to dynamic, AI-generated UIs—reducing boilerplate and enabling richer user experiences. With enterprise adopters like Toyota and Talabat, Flutter is proving its scalability beyond mobile into automotive, middleware, and full-stack cloud apps. Expect these capabilities to deepen at Google I/O and beyond.
