Cursor rules for Flutter development with expert integration

Cursor rules for Flutter development with expert integration is a skill for Claude Code, Codex from AmariahAK/atlarix-skills. It costs 8 tokens per session (681 once invoked), scanned A, original, Apache-2.0.

A set of coding guidelines for building Flutter apps, Google's framework for making mobile, web, and desktop apps from one codebase. It suggests approaches for app structure, state management, dependency injection, errors, localization, and platform-specific design.

In plain words
What is it for?
Use it when designing or reviewing Flutter app structure, managing changing screen data, connecting services, handling errors, supporting multiple languages, and following iOS or Android design conventions.
Why use it?
It gives a project consistent development practices instead of leaving architecture and common implementation choices to chance. The suggested structure should be adapted to the existing codebase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Cursor rules for Flutter development with expert integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
