Learning faster with Antigravity

A Flutter developer describes how they used Antigravity (Google's AI coding assistant) and a structured iterative workflow to build a Flutter frontend for a Python-based ADK (Agent Development Kit) agent — a language and framework they had no prior experience with. The approach involved creating a reusable 'skill' (a set of reference docs and instructions) that guided an AI 'coder' agent through phases: analyzing the backend agent, writing usage/architecture/design specs, and generating code. A separate 'author' agent helped evaluate output and refine the skill after each of 13 iterations. The post walks through specific bugs fixed along the way — network permissions, markdown rendering, SSE partial event aggregation, and more — and shares the resulting skill on GitHub.
