This CL adds a lint that reports when a user uses a pair of angled brackets which are not in a code block, nor a code span, and is not an autolink. Updated the `rules.json` for the new lint as well.

Linter for Dart
The Dart Linter package defines lint rules that identify and report on "lints" found in Dart code. Linting is performed by the Dart
analysis server and the dart analyze command in the Dart command-line tool.
Installing
The linter is bundled with the Dart SDK; if you have an updated Dart SDK already, you're done!
Usage
The linter gives you feedback to help you catch potential errors and keep your code in line with the published
Dart Style Guide. Enforceable lint rules (or "lints") are cataloged here and can be configured via an
analysis options file. The linter is run from within the dart analyze command-line tool shipped with the
Dart SDK. Assuming you have lints configured in an analysis_options.yaml file at the root of your project with these contents:
linter:
rules:
- annotate_overrides
- hash_and_equals
- prefer_is_not_empty
you could lint your package like this:
$ dart analyze .
and see any violations of the annotate_overrides, hash_and_equals, and prefer_is_not_empty rules in the console.
To help you choose the rules you want to enable for your package, we have provided a complete list of rules
with lints recommended by the Dart team collected in package:lints. Lints recommended for Flutter apps, packages,
and plugins are documented in package:flutter_lints.
If a specific lint warning should be ignored, it can be flagged with a comment. For example,
// ignore: camel_case_types
class whyOhWhy { }
tells the Dart analyzer to ignore this instance of the camel_case_types warning.
End-of-line comments are supported as well. The following communicates the same thing:
class whyOhWhy { // ignore: camel_case_types
To ignore a rule for an entire file, use the ignore_for_file comment flag. For example,
// ignore_for_file: camel_case_types
...
class whyOhWhy { }
tells the Dart analyzer to ignore all occurrences of the camel_case_types warning in this file.
As lints are treated the same as errors and warnings by the analyzer, their severity can similarly be configured in an options file. For example, an analysis options file that specifies
linter:
rules:
- camel_case_types
analyzer:
errors:
camel_case_types: error
tells the analyzer to treat camel_case_types lints as errors. For more on configuring analysis see the analysis option file docs.
