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.

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_chars lint from the analyzer.
  • dart-modern-features: For idiomatic usage of modern Dart features like Pattern Matching (useful for deep JSON extraction), Records, and Switch Expressions.

# 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.

## 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:**
```dart
final pem = '-----BEGIN RSA PRIVATE KEY-----\n' +
    base64Encode(fullBytes) +
    '\n-----END RSA PRIVATE KEY-----';
```

**Prefer:**
```dart
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_chars` lint from the analyzer.

## Related Skills

- **[dart-modern-features]**: For idiomatic
  usage of modern Dart features like Pattern Matching (useful for deep JSON
  extraction), Records, and Switch Expressions.
