flutter-project-rules

flutter-project-rules is a cursor rule for Cursor from paulpham157/paul-s-cursor-rules. It costs 0 tokens per session (785 once invoked), scanned A, original, MIT.

A set of Flutter project-structure rules for organizing Dart code by feature, with separate areas for data access, business logic, user-interface screens, and shared code.

In plain words
What is it for?
Structuring Flutter features such as authentication or products, and naming their models, repositories, screens, controllers, and widgets.
Why use it?
It reduces uncertainty about where files belong and encourages a consistent structure as the app grows.

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

flutter-project-rules 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 3d 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.

    • core/: Core app logic (networking, errors, DI).
    • app.dart: Root widget.
    • main.dart: Entry point.
  • features/ Structure:

    • <feature_name>/: A feature (e.g., authentication, products).
    • data/: Data access.
    • models/: Data Transfer Objects (DTOs).
    • <feature_name>_repository.dart: Data access logic.

    • Feature Isolation: Self-contained feature code.
    • Separation of Concerns: Separate data, logic, and UI.
    • Single Responsibility: One purpose per class/file.
    • DRY: Avoid code duplication.
    • Prefer Feature-Specific: Prioritize feature-level placement.

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.
