The legacy debug adapters would scan all output for stack frames but when building the new adapters I only parsed stderr (because the stack frame parsing captures quite a lot and it seemed unnecessary). It turned out many users appreciated the IDE linking up stack traces in stdout too (because their exception logging framework may handle exceptions and print them this way, or they might have helpers to print the current stack trace to aid debugging). This marks `parseStackFrames` as deprecated from `sendOutput` and scans all output for frames, while filtering out things that don't look like Dart URIs before calling `lookupResolvedUris` to try and avoid making general output async/slow. If Flutter considers deprecations a bot failure, this will need to be rolled in manually.

A package used to spawn the Dart Developer Service (DDS), which is used to communicate with a Dart VM Service instance and provide extended functionality to the core VM Service Protocol.
Functionality
Existing VM Service clients can issue both HTTP, websocket, and SSE requests to a running DDS instance as if it were an instance of the VM Service itself. If a request corresponds to an RPC defined in the VM Service Protocol, DDS will forward the request and return the response from the VM Service. Requests corresponding to an RPC defined in the DDS Protocol will be handled directly by the DDS instance.
SSE Support
For certain web clients it may be preferable or required to communicate with DDS using server-sent events (SSE). DDS has an SSE handler listening for requests on /$debugHandler.
SSE and package:vm_service example
import 'package:sse/sse.dart';
import 'package:vm_service/vm_service.dart';
void main() {
// Establish connection with DDS using SSE.
final ddsChannel = SseClient('${ddsUri}\$debugHandler');
// Wait for ddsChannel to be established
await ddsChannel.onOpen.first;
// Initialize VmService using the sink and stream from ddsChannel.
final vmService = VmService(
ddsChannel.stream,
(e) => ddsChannel.sink.add(e),
);
// You're ready to query DDS and the VM service!
print(await vmService.getVersion());
}
