What it does
Dart Best Practices is an agent skill from kevmoo/dash_skills. General best practices for Dart development. Covers code style, effective Dart, and language features.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/evals.json`).
It sits in Mobile, covering Cross-platform mobile apps. It works with Dart. The repository describes itself as: Agent Skills for Dart and Flutter ecosytem. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Cross-platform mobile apps
Example prompts
- “/dart-best-practices”
Workflow steps
2 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 397a703. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are dart).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Dart Best Practices loads about 709 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 281 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Dart Best Practices
1. When to use this skill
Use this skill when:
- Writing or reviewing Dart code.
- Looking for guidance on idiomatic Dart usage.
When NOT to use (Abstention Guardrails)
Do NOT apply this skill or refactor code when:
- Public API Breaking Changes: Refactoring would alter public API contracts, return types, or parameter signatures in published packages without a coordinated major SemVer bump.
- Dogmatic Micro-Optimizations: Rewriting clear, readable code for negligible theoretical gains (e.g. replacing clear string concatenation in a simple one-line log message with multiline quotes).
- Domain-Specific or Code-Generated Files: Generated files (
*.g.dart,*.freezed.dart, protobufs) or files where line lengths and string layouts are managed by code generators. - Explicit Type Annotations in Public Interfaces: Replacing explicit type
annotations with
varorfinalwhere explicit types document the public API surface or disambiguate complex generics.
2. Best Practices
Multi-line Strings
Prefer using multi-line strings (''') over concatenating strings with + and
\n, especially for large blocks of text like SQL queries, HTML, or PEM-encoded
keys. This improves readability and avoids lines_longer_than_80_chars lint
errors by allowing natural line breaks.
Avoid:
final pem = '-----BEGIN RSA PRIVATE KEY-----\n' +
base64Encode(fullBytes) +
'\n-----END RSA PRIVATE KEY-----';Prefer:
final pem = '''
-----BEGIN RSA PRIVATE KEY-----
${base64Encode(fullBytes)}
-----END RSA PRIVATE KEY-----''';Line Length
Avoid lines longer than 80 characters, even in Markdown files and comments. This ensures code is readable in split-screen views and on smaller screens without horizontal scrolling.
Prefer: Target 80 characters for wrapping text. Exceptions are allowed for long URLs or identifiers that cannot be broken.
Discovery
Multi-line Strings
To find candidates for multi-line strings, search for string concatenation with
+ involving newlines:
- Regex:
['"]\s*\+\s*['"] - Regex:
\+\s*['"].*\\n
Line Length
- Rely on the
lines_longer_than_80_charslint from the analyzer.
