kevmoo 193e53076c Use ^3.12.0-0 instead of -edge
Otherwise folks on ~latest bits from Flutter can't run pub!

Resolving dependencies in `/Users/kevmoo/github/dart/sdk`...
The current Dart SDK version is 3.12.0-261.0.dev.

Because dart_runtime_service_vm requires SDK version ^3.12.0-edge, version solving failed.

Dart Runtime Services

Implementations of various Dart developer services based on package:dart_runtime_service.

Shared frontend, pluggable backend

package:dart_runtime_service provides a simple interface to create Dart services with common platform-agnostic features and behaviors, while also allowing for configuration of custom service backends. This removes the need for individual services to implement functionality common to most services, including:

  • Launching and advertising a server
  • Handling connections via various protocols (web sockets, SSE, HTTP)
  • Authentication code verification
  • Notification routing via stream subscriptions
  • Client-registered service extension routing
  • DevTools hosting

Roadmap

There are currently two planned runtime service implementations, with a focus on replacing dart:_vmservice and package:dwds:

  • package:dart_runtime_service_vm: an implementation of the Dart VM service protocol which can interact with the native runtimes. To be launched directly as an isolate by dart and dartaotruntime.

  • package:dart_runtime_service_web: an implementation of the Dart VM service protocol which serves as a proxy to interact with a running web application. To eventually be launched using dart web-development-service by developer tooling responsible for launching and managing DDC-based applications.

Future candidates for migration include:

  • package:dtd_impl: the implementation of the Dart Tooling Daemon (DTD), which implements a similar protocol to the VM service protocol.

  • package:dds: the implementation of the Dart Development Service (DDS), which provides extensions to the VM service protocol. DDS reimplements much of the common functionality provided by package:dart_runtime_service, particularly around client management, stream subscriptions, and service extension routing.
