Write Dart everywhere: Support for Firebase Functions is here!

Tired of switching between Dart for your frontend and Node.js for your backend? Join Kevin Moore and Roddy Davis live from Google Cloud Next '26 as they reveal one of the most requested features in the Google developer ecosystem: Dart support for Firebase Functions. For the first time, Flutter and Dart developers can build truly isomorphic applications. You can now take the same business logic, the same classes, and the same type safety from your mobile app and deploy it directly to the backend without touching JavaScript, Go, or Python. Why Dart on the Server is a Massive Win: Isomorphic Development: Share code between your Flutter frontend and your Firebase backend seamlessly. Insane Performance: Dart compiles to native ARM/AMD64 binaries. This means no JIT "warming up" and cold starts measured in milliseconds. Scale to Zero: Because it starts so fast, you can confidently use Cloud Run’s scale-to-zero feature to save costs without punishing your users with latency. Small & Portable: Demos show binary sizes as small as 10MB, compared to hundreds of megabytes for traditional runtime environments. The "Impeller" Trick: Kevin explains how Flutter uses the same "engine-first" strategy as triple-A game engines (like Unreal or Unity) to ensure that your pixels and performance are identical whether you're on iOS, Android, a web browser, or even an LG smart TV. Live Demo & "The Brave Deploy": Watch as the team: Runs a Flutter app and Dart backend locally using Firebase Emulators. Uses Hot Reload to change a UI element (swapping rockets for gold medals) across the entire stack in seconds. Performs a live production deploy to Cloud Run on air (and survives a minor network glitch!) to show just how fast the cycle from "code to cloud" has become. "We want developers to think about what they want to build first, and pick the platform second. Whether it's a Raspberry Pi, an iPhone, or a serverless function—it's all just Dart."
