Guidelines for handling long lines in Dart code to adhere to the 80-column rule. The `lines_longer_than_80_chars` lint.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Dart Long Lines

## 1. When to use this skill

Use this skill when:

- Writing Dart code that might exceed the 80-column limit.
- Refactoring code to comply with the `lines_longer_than_80_chars` lint.
  Reference: https://dart.dev/tools/linter-rules/lines_longer_than_80_chars

### When NOT to use (Abstention Guardrails)

Do NOT break lines or alter code when:

- **Unbreakable URLs & URIs**: Lines contain long HTTP/HTTPS URLs, import URIs,
  or file paths where breaking them across lines would invalidate the link.
- **Complex Regular Expression Literals**: Long RegExp patterns
  (`RegExp(r'...')`) where inserting whitespace or line breaks changes the
  matching semantics.
- **ASCII Art, Tables, or Preformatted Diagrams**: Preformatted text blocks,
  table rows, or ASCII diagrams inside comments or strings where wrapping lines
  destroys visual alignment.
- **Prior to Automated Formatting**: Do NOT manually break code lines before
  running `dart format`. Let `dart format` handle code wrapping automatically;
  only manually wrap comments, docs, and multi-line strings that the formatter
  does not re-wrap.

How to install

The exact contents, by fingerprint

mdr add kevmoo/dash_skills/dart-long-lines@sha256:6fc182eba347e6e8

The line at the top of this page pins the label git:20260913.6c39005, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
