Rich and Dynamic User Interfaces With Flutter and Generative UI
Article Summary
Abdallah W Shaban from Google's Flutter team just dropped GenUI SDK—a way to let AI generate entire interactive UIs on the fly, not just text responses. Think magazine-style layouts that adapt to each user, built by Gemini in real-time.
Flutter's new GenUI SDK (now in alpha) enables developers to create dynamic, personalized interfaces where LLMs like Gemini generate not just content, but the actual UI widgets to display it. The SDK orchestrates a loop between user input, AI agents, and Flutter widgets, transforming conversations into rich visual experiences. It's the same tech powering Gemini app's new visual layout feature.
Key Takeaways
- AI agent generates both content AND the UI structure to display it
- Built on upcoming A2UI protocol for LLM-generated interfaces
- Works with Gemini API, Firebase AI, or custom LLM providers
- Sample apps include landscape design tool with image analysis
- Roadmap includes progressive rendering and full-screen composition
GenUI SDK lets Flutter apps move beyond static layouts to AI-driven interfaces that adapt UI components in real-time based on user context and preferences.
About This Article
Developers building GenAI applications wanted to move beyond simple text chatbots. They needed to create rich, interactive experiences that felt personalized and looked consistent across different platforms.
Abdallah W Shaban's team built GenUI SDK to coordinate how information flows between Flutter widgets and AI agents. The A2UI protocol serializes the UI that LLMs generate, making sure it follows custom widget catalogs and branding guidelines.
The SDK lets developers generate dynamic, magazine-style layouts with interactive components like sliders, buttons, and date pickers in real-time. Gemini's new visual layout feature now uses this approach on iOS and Android.
