1	# Dart Long Lines
2
3	## 1. When to use this skill
4
5	Use this skill when:
6	- Writing Dart code that might exceed the 80-column limit.
7	- Refactoring code to comply with the `lines_longer_than_80_chars` lint.
8	Reference: https://dart.dev/tools/linter-rules/lines_longer_than_80_chars
9
10	## Discovery
11
12	To find lines that exceed the limit:
13
14	### Automated Analysis
15	The most reliable way to find long lines is to use the Dart analyzer:
16	- Command: `dart analyze`
17	- Lint: `lines_longer_than_80_chars`
18
19	### Manual Search
20	To search for long lines using regex:
21	- Regex: `^.{81,}$` (Matches any line with 81 or more characters).
22
23	## 2. Guidelines
24
25	### Format First
26	Always run `dart format` before manually breaking long lines. The formatter
27	often automatically fixes long lines, especially in generated code, and
28	applies standard Dart styling rules.
29
30	### Code Comments
31	Break long code comments (`//`) cleanly at word boundaries to ensure lines do
32	not exceed 80 characters. Maintain tight formatting and avoid unnecessary
33	vertical space.
34
35	### Documentation Comments (`///`)
36	- Apply the same line-breaking rules as for code comments.
37	- Avoid breaking markdown link blocks like `[name]` or
38	`[text](http://example.com)` across lines. Place them on their own line if
39	they exceed the limit.
40	- Start doc comments with a single summary sentence, followed by a blank line
41	before the rest of the comment. It is okay to break this first sentence
42	across multiple lines to fit the 80-column limit.
43	- Avoid unresolved references or dangling sentences.
44
45	### Long Strings
46	- Use adjacent string literals (e.g., `'part 1 ' 'part 2'`) to break long
47	strings. Break at word boundaries.
48	- If a single-line string contains newline characters (`\n`) or if there are
49	consecutive `print` statements, consider migrating to a multi-line string
50	literal (`'''`).
51
52	### Format and Analyze After Changes
53	- Run `dart format` and `dart analyze` after making changes.
54	- Be aware that splitting strings may trigger new lints (e.g.,
55	`prefer_single_quotes` if a double-quoted string is split into parts that
56	no longer contain single quotes).
57
58	## 3. Examples
59
60	### Documentation Comment Link
61	Avoid:
62	```dart
63	/// This is a long doc comment that contains a link to [a very long
64	/// URL](http://example.com/very/long/url/that/exceeds/eighty/chars).
65	```
66
67	Prefer:
68	```dart
69	/// This is a long doc comment that contains a link to [a very long URL][ref].
70	///
71	/// [ref]: http://example.com/very/long/url/that/exceeds/eighty/chars
72	```
73
74	### Adjacent String Literals
75	Prefer:
76	```dart
77	final longString = 'This is a very long string that needs to be broken '
78	'across multiple lines to stay under the limit.';
79	```
80
81	### Multi-line String Migration
82	Avoid:
83	```dart
84	print('This is line 1\nThis is line 2 that is also quite long\nThis is line 3 which makes the whole thing exceed eighty characters');
85	```
86
87	Prefer:
88	```dart
89	print('''This is line 1
90	This is line 2 that is also quite long
91	This is line 3 which makes the whole thing exceed eighty characters''');
92	```
