That’s a wrap: Everything Flutter at Google I/O 2026

That’s a wrap: Everything Flutter at Google I/O 2026

What a week! Google I/O 2026 is officially in the books. It’s time to recap the whirlwind of updates for the Flutter and Dart communities.

The onsite star was a full-sized specialty coffee shop in the absolute center of Google I/O, built entirely with Flutter GenUI, where nanobanana-generated artwork was printed right on the coffee foam.

But don’t worry if you weren’t able to make it to Shoreline. We recorded every moment and more, now available for on-demand viewing on the Flutter YouTube channel.

📺 Watch every session

From keynote to tech session, we can’t wait for you to see every moment of Flutter from I/O 2026.

🌟 What’s new in Flutter

A few of the highlights:

• Flutter 3.44 & Dart 3.12: These releases brought major advancements with Agentic Hot Reload, GenUI with a showcase from Li-Te Cheng on the DeepMind team, Toyota has embedded Flutter in the 2026 RAV4, improved rendering performance with Impeller, decoupling of Material and Cupertino UI from the framework, Swift Package Manager is on by default for iOS and macOS, Canonical now leads the Flutter desktop roadmap, and significant updates to platform-specific fidelity with HCPP.

🌟 Vibe once, run anywhere with Antigravity and Flutter

• What you’ll learn: A technical introduction to Antigravity, a new IDE focused on building with agents. You will learn how to leverage “vibe-based” development to create experiences that adapt and run across all platforms seamlessly.

• Why it matters: It provides the architectural roadmap for shifting from “hard-coded” layouts to “vibe-based” generative experiences, allowing your app to adapt to user needs on the fly.

How to write really good Flutter code

• What you’ll learn: Principles for writing high-quality, maintainable Flutter code, and how modern tooling — including Widget Previews, DevTools, MCP servers, and Skills make it easier than ever to build great apps.

• Why it matters: AI can write code faster than ever, but best practices and robust tooling provide the quality control needed to keep Flutter applications maintainable over time.

Introducing the Full-stack developer series

• What you’ll learn: Not a lot, but this less-than-two-minute video is fun and introduces the four episode series.

Full-stack dev series #1 — Flutter + A2UI = GenUI

• What you’ll learn: A technical deep dive into the building blocks of Generative UI, with a top-to-bottom conversion of a text-based chatbot into an agent that creates its own UI and understands how you interact with it.

• Why it matters: Not only can GenUI turn a slow, text-based experience into a delightful one, but it opens up new user experience patterns in which static designs and route hierarchies become flexible, on-demand UI tailored to individual users and their goals.

Full-stack dev series #2 — Full-stack Dart

• What you’ll learn: How to unify your app’s tech stack and eliminate context switching by using Dart for both frontend and backend logic. This video builds a complete serverless application live, using Dart for Firebase Cloud Functions.

• Why it matters: This approach improves development velocity and reduces costs by allowing teams to share logic, tooling, and expertise across the entire application stack.

Full-stack dev series #3 — Introducing Genkit Dart

• What you’ll learn: How to create Genkit flows that power your app’s backend and frontend, and discover the essential security steps needed to protect your AI endpoints. This video covers everything from initial setup to implementing rate limits and caching to keep your project secure and cost-effective.

• Why it matters: Genkit bridges the gap between prototyping and shipping reliable AI applications. It simplifies building AI into existing code by providing a unified SDK across multiple languages and models, alongside robust debugging and monitoring tools. Genkit works as a backend, but also in your Flutter app!

Full-stack dev series #4 — Everything you don’t know about building great native apps with Flutter

• What you’ll learn: All the small additions we’ve made to Flutter to make a compelling native experience, from embracing native workflows, supporting new languages for Dart binding generation, or new rendering methods that balance the needs of host UIs and Flutter

• Why it matters: Flutter is not about finding a “lowest common denominator.” It is about providing a high-fidelity, high-performance framework that respects and enhances the native platforms it runs on.

…and that’s it!

Thank you all for joining along as we brewed up one of our favorite I/Os yet. Stay tuned for more blog posts, videos and docs about everything we announced, and all of the community events we’re attending starting next month.
