When to use this skill\nUse this skill when:\n-   Writing or reviewing Dart code.\n-   Looking for guidance on idiomatic Dart usage.\n\n## 2. Best Practices\n\n### Multi-line Strings\nPrefer using multi-line strings (`'''`) over concatenating strings with `+` and\n`\\n`, especially for large blocks of text like SQL queries, HTML, or\nPEM-encoded keys. This improves readability and avoids\n`lines_longer_than_80_chars` lint errors by allowing natural line breaks.\n\n**Avoid:**\n```dart\nfinal pem = '-----BEGIN RSA PRIVATE KEY-----\\n' +\n    base64Encode(fullBytes) +\n    '\\n-----END RSA PRIVATE KEY-----';\n```\n\n**Prefer:**\n```dart\nfinal pem = '''\n-----BEGIN RSA PRIVATE KEY-----\n${base64Encode(fullBytes)}\n-----END RSA PRIVATE KEY-----''';\n```\n\n### Line Length\nAvoid lines longer than 80 characters, even in Markdown files and comments.\nThis ensures code is readable in split-screen views and on smaller screens\nwithout horizontal scrolling.\n\n**Prefer:**\nTarget 80 characters for wrapping text. Exceptions are allowed for long URLs\nor identifiers that cannot be broken.\n\n## Discovery\n\n### Multi-line Strings\nTo find candidates for multi-line strings, search for string concatenation\nwith `+` involving newlines:\n- **Regex**: `['\"]\\s*\\+\\s*['\"]`\n- **Regex**: `\\+\\s*['\"].*\\\\n`\n\n### Line Length\n- Rely on the `lines_longer_than_80_chars` lint from the analyzer.\n\n## Related Skills\n\n- **[dart-modern-features]**: For idiomatic\n  usage of modern Dart features like Pattern Matching (useful for deep JSON\n  extraction), Records, and Switch Expressions.\n\n[dart-modern-features]: https://github.com/kevmoo/dash_skills/blob/main/skills/dart-modern-features/SKILL.md\n","tagline":"|-","category":"automation","tags":["agent-skill"],"author":"kevmoo","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"kevmoo/dash_skills","creatorName":"kevmoo","creatorUrl":"https://github.com/kevmoo","sourceUrl":"https://github.com/kevmoo/dash_skills/tree/main/skills/dart-best-practices","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/kevmoo-dart-best-practices#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
