Agentic apps with Gemini and Flutter

The future of app interaction is here, and it can be summed up in one word: agents. In this workshop, we'll explore the next generation of user experiences through "agent apps." We'll discover how to elevate the UX of our apps to the next level using the power of Generative AI, AI Agents, and the tools available in the Flutter ecosystem. We'll have a hands-on session where you can program your own agent app and take your idea home fully functional. Get ready for a session that will change the way you think about software interaction, where we'll see how Gemini can empower your apps to be smarter, more proactive, and more autonomous.
