meta 0.5.20

1. Depend on it

Add this to your package's pubspec.yaml file:

dependencies:
  meta: 0.5.20

If your package is an application package you should use any as the version constraint.

2. Install it

If you're using the Dart Editor, choose:

Menu > Tools > Pub Install

Or if you want to install from the command line, run:

$ pub install

3. Import it

Now in your Dart code, you can use:

import 'package:meta/meta.dart';
