## AI overview

This article describes how a team used Google's Antigravity and Flutter to build and launch DashLander, a moonlander-style game set on procedurally generated asteroids. It explains how coding agents handled assets, code, testing, marketing, and deployment, and why Flutter's cross-platform model and Dart's strong typing can support agentic development.

## Source excerpt

co-authored with Rody Davis Coding agents and the way we use them has already dramatically evolved since their arrival just a handful of months ago. Initially, the focus was heavily on observation -- reviewing every single output line by line. But as models rapidly increased in capability, the industry shifted toward true agentic engineering. Today, developers, PMs, and designers are wearing multiple hats, focusing on lofty conceptual goals and letting agents tackle the individual components. To explore this new frontier, our team wanted to build an experience that showcased this exact workflow. We wanted to build a game, generate its assets, write the marketing page, and deploy the whole thing, all using Google's premiere AI-native platform: Antigravity. Antigravity brings the best of Google into one place, using a tight feedback loop of planning, acting, and verifying. It creates artifacts, writes code, runs tests, and even clicks buttons in your UI to ensure it actually completed the task correctly. The result of our agentic adventure is DashLander -- a moonlander-style game set on procedurally generated asteroids. Here is the story of how we built it. Why Flutter in the AI era? A lot of people might be thinking: If agents can write native code, why not just have them write Android, iOS, and web apps entirely separately? That is a valid question; and is what originally inspired the concept of Flutter as a "Vibe once, run anywhere" UI toolkit. Having a single source of truth is just as important for AI as it is for humans. By having an agent write a single, cross-platform app, teams can eliminate the subtle bugs that inevitably creep in between different languages or platform-specific paradigms. Furthermore, Dart's strong typing gives LLMs excellent feedback. Languages with looser typing systems require dramatically more analysis by the LLM to know whether a given piece of code is correct across all scenarios. Flutter and Dart, on the other hand, use their analysis
