Hello **raywenderlich** team 👋

The beautifully displayed code blocks in Raywenderlich’s online books and articles are one of the reasons why I enjoy the site 😍

But unlike the books and articles, the code blocks in the forum do not highlight **Dart** code correctly. The example Dart code further below is detected as **Rust** by the _Highlight.js_ library that Discourse utilises, and in a [post](https://forums.kodeco.com/t/chapter-2-about-checking-type/171913/2) I made on another topic, the Dart code was detected as **Python**

A potential solution might be to check if Dart is listed under the `highlighted languages` setting in Discourse’s admin area and enable it, if necessary.

I have tested the preformatted text block on Swift, Dart and Objective-C code, trying both the standard opening tag for automatic detection ````` and the one to set a language.

**Swift** code is detected, but cannot be specifically set using ` ```swift`  
So Swift might also not be enabled under `highlighted languages` setting.

**Dart** is not detected and cannot be set using ` ```dart`

**Objective-C** is detected automatically and can also be set using ` ```objectivec`

Thanks for reading 👍

Example code from [highlight.js demo](https://highlightjs.org/static/demo/) page:

```auto
library app;
import 'dart:html';

part 'app2.dart';

/**
 * Class description and [link](http://dartlang.org/).
 */
@Awesome('it works!')
class SomeClass<S extends Iterable> extends BaseClass<S> implements Comparable {
  factory SomeClass(num param);
  SomeClass._internal(int q) : super() {
    assert(q != 1);
    double z = 0.0;
  }

  /// **Sum** function
  int sum(int a, int b) => a + b;

  ElementList els() => querySelectorAll('.dart');
}

String str = ' (${'parameter' + 'zxc'})';
String str = " (${true ? 2 + 2 / 2 : null})";
String str = " ($variable)";
String str = r'\nraw\';
String str = r"\nraw\";
var str = '''
Something ${2+3}
''';
var str = r"""
Something ${2+3}
""";

checkVersion() async {
  var version = await lookUpVersion();
}

```

Thanks for bringing this up! I’m forwarding it to the team.

Thank you! The preformatted text block in this topic and in the linked post, are now both highlighted correctly as Dart 👍
