A2UI is an open protocol enabling AI agents to safely return structured UI components (e.g., date pickers, maps) instead of plain text; integrated with Gemini Enterprise, it renders rich, interactive interfaces natively in chat surfaces—and supports cross-framework (Lit/Flutter/Angular) and transport-agnostic (A2A/SSE/WebSocket) deployment.

This article introduces how to build production-grade REST APIs using Dart and Serverpod, compares the development philosophy of Serverpod with traditional manual approaches (like Shelf), and demonstrates the full workflow from project creation to code generation, model definition, and API implementation.

Dart Frog 是一个基于 Shelf 的轻量级后端框架，采用文件系统路由模型，适合 Flutter 工程师构建 REST API。

In Flutter development, the 'It Works on My Machine' mindset can lead to production issues.
