An unlisted package for sharing code for service events and stream management between Dart SDK internal services.

The Dart Developer Service and Dart Tooling Daemon are the main consumers of this package.

Expected SLO: this package is maintained for our own tooling; we may not be able to respond to all issues and may only address the ones that we ourselves encounter.

Details

This package helps handle some of the plumbing required to setup client communication for a service. The main behavior that it helps with is:

  • StreamManager
    • allows a client to subscribe/cancel to a stream with streamListen/streamCancel.
    • allows a client to post a message to a stream with postEvent.
  • Client, an interface that ensures the client is equipped to:
    • handle method requests with sendRequest.
    • handle receiving a message sent to a stream with streamNotify.
  • ClientManager, keeps track of clients connected to a service.
    • addClient should be called when a client connects to your service.
    • removeClient should be called when it disconnects.
