As of Dart 2, pub no longer supports pub build, pub serve, or transformers. They’re replaced by the build system, which includes the build_runner tool.

For information about building and serving apps in Dart 2, see the following:

• Web development:
  • Setup for Angular development (v5)
  • Deployment (v5)
  • Web-specific build_runner documentation
• General:
  • Build system
  • Build system documents, including getting started with build_runner

If you use Dart 1.x for web development, see the following:

• Setup for Angular development (v4)
• Deployment (v4)
• Pub command reference:
  • pub build
  • pub serve

If you maintain a transformer, see the following:

• Assets and Transformers in the archived Dart site
• Writing a Pub Transformer in the archived Dart site

For help in switching from Dart 1.x to Dart 2, see the Dart 2 migration guides:
