This question came up in another change, about whether a client would have hanging requests if the other DTD client providing the service disconnected. This adds a test to ensure that any pending requests are terminated with an error. It also tidies up some other tests to give better errors if they fail.

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.
- allows a client to subscribe/cancel to a stream with
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.
- handle method requests with
ClientManager, keeps track of clients connected to a service.addClientshould be called when a client connects to your service.removeClientshould be called when it disconnects.
