package_api_docs

DO provide doc comments for all public APIs.

As described in the pub package layout doc, public APIs consist in everything in your package's lib folder, minus implementation files in lib/src, adding elements explicitly exported with an export directive.

For example, given lib/foo.dart:

export 'src/bar.dart' show Bar;
export 'src/baz.dart';

class Foo { }

class _Foo { }

its API includes:

• Foo (but not _Foo)
• Bar (exported) and
• all public elements in src/baz.dart

All public API members should be documented with /// doc-style comments.

GOOD:

/// A Foo.
abstract class Foo {
  /// Start foo-ing.
  void start() => _start();

  _start();
}

BAD:

class Bar {
  void bar();
}

Advice for writing good doc comments can be found in the Doc Writing Guidelines.
