Google I/O 2026 brought a wave of Flutter and Dart announcements. Flutter 3.44 and Dart 3.12 shipped with Agentic Hot Reload, Generative UI (GenUI), improved Impeller rendering, Swift Package Manager on by default for iOS/macOS, and Canonical taking over the Flutter desktop roadmap. Toyota embedded Flutter in the 2026 RAV4. A new IDE called Antigravity introduces agent-based 'vibe' development for cross-platform apps. A four-part full-stack developer series covers GenUI with A2UI, full-stack Dart using Firebase Cloud Functions, Genkit Dart for AI-powered backends, and native app improvements. Genkit Dart bridges prototyping and production AI apps with a unified SDK, debugging tools, and security features like rate limiting and caching.
