flutter-accessibility

A set of accessibility rules for Flutter Dart files. Accessibility means making an app usable with screen readers, larger text, keyboard navigation, and different visual abilities.

In plain words
What is it for?
Use it while writing or reviewing Flutter UI code to add semantic labels, check color contrast, support text scaling, and test screen-reader behavior.
Why use it?
It guides developers toward readable contrast, scalable text, descriptive controls, and correct behavior with VoiceOver on iOS and TalkBack on Android.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-accessibility 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 2d 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 it actually says

Accessibility (A11Y)

Implement accessibility features to empower all users, assuming a wide variety of users with different physical abilities, mental abilities, age groups, education levels, and learning styles.

Key Principles

  • Color Contrast: Ensure text has a contrast ratio of at least 4.5:1 against its background.
  • Dynamic Text Scaling: Test your UI to ensure it remains usable when users increase the system font size.
  • Semantic Labels: Use the Semantics widget to provide clear, descriptive labels for UI elements.
  • Screen Reader Testing: Regularly test your app with TalkBack (Android) and VoiceOver (iOS).

Testing

  • Test with screen readers enabled on both iOS and Android
  • Verify all interactive elements have appropriate labels
  • Ensure proper focus order for keyboard navigation
  • Check color contrast ratios meet WCAG standards
Changes

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.

flutter-accessibility is a cursor rule published in the GitHub repository Desquared/agents-rules-skills (4 stars, last pushed 18d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 209 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
