Dart Write Documentation skill: what it does and how to install it

What it does. Applies Effective Dart conventions to public Dart API comments, using ///, concise first paragraphs, appropriate openers, Markdown links, and prose instead of Javadoc tags. It also covers annotation placement, inherited docs, getter/setter pairs, constructor links, and dart analyze verification.

When to use it. Use when writing or updating documentation for Dart declarations. Private members are excluded unless explicitly requested, and dart doc is optional for checking generated output.
