This adds the `stackTrace` for an exception to the error text (when available). At first I thought this might be noisy, but it turns out other debuggers in VS Code are already doing it - for example see JS here: https://github.com/dart-lang/sdk/issues/62466#issue-3842487864 I'm not certain why, but we don't have the `stackTrace` when we break on the `throw`, however in that case the debuggers call stack is already at the correct location, so I don't think this is a problem. Video of how this looks in VS Code is at https://github.com/dart-lang/sdk/issues/62466#issuecomment-3801129877 Fixes https://github.com/dart-lang/sdk/issues/62466 Change-Id: Id2d3054f066004740e8640516a5903fe97b4808c Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/475202 Reviewed-by: Ben Konyi <bkonyi@google.com> Commit-Queue: Ben Konyi <bkonyi@google.com> Reviewed-by: Jessy Yameogo <yjessy@google.com>
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());
}
