Arenukvern/mcp_flutter — reverse-engineered prompt

Build me a Flutter developer helper that lets an AI coding assistant actually look at and control a running Flutter app while I’m working on it.

I want it to run as a Dart MCP server plus a Flutter package I can add to any debug app. Once connected, the assistant should be able to inspect the screen, take semantic snapshots and screenshots, tap buttons, type into fields, scroll, navigate, hot reload, hot restart, read recent logs, see errors, and evaluate simple Dart expressions. It should also let the Flutter app expose its own custom tools and resources at runtime, so the assistant can use app specific actions without me hardcoding everything in the server.

Please include a simple command line setup flow, agent setup for tools like Claude Code, Cursor, Codex, and Cline, clear docs, a small test Flutter app, and troubleshooting for connection issues. Keep it focused on debug mode and make the setup feel like a few commands. Look up current MCP and Flutter docs online if needed.
