Summary class Null safety

An annotation that provides a short description of a class for use in an index.

Usually the first paragraph of the documentation for a class can be used for this purpose, but on occasion the first paragraph is either too short or too long for use in isolation, without the remainder of the documentation.

/// A famous cat.
///
/// Instances of this class can hunt small animals.
/// This cat has three legs.
@Category(<String>['Animals', 'Cats'])
@Category(<String>['Cute', 'Pets'])
@DocumentationIcon('https://www.examples.net/docs/images/icons/pillar.jpeg')
@Summary('A famous three-legged cat.')
class Pillar extends Cat {
  // ...code...
}

  • Category, to help place the class in an index.
  • DocumentationIcon, which is used to give the URL to an image that represents the class.
