[DART Plugin] breakpoint inside lib folder?

Hi,

My project is layouted as below:

// -----

>> In "bin" directory :

library gtsi_web;

import 'package:redstone/server.dart' as app;
import 'package:shelf_static/shelf_static.dart';

part '../lib/endpoints.dart';

main() {
 app.setShelfHandler(createStaticHandler(env(ENV_BASEDIR_WEB), defaultDocument: "index.html", serveFilesOutsidePath: true));
 app.setupConsoleLog();
 app.start(port: 9090);
}

>> In "lib" directory:

part of gtsi_web;

@app.Route("/")
itWorks() => "It works!";

// -----

My content root is defined to: D:\NIO\dev\workspaces-idea\chicago\gtsi_web (below, there are bin/ and lib/ folders) without any exclusion.

Setting a breakpoint in endpoints.dart is not taken into account. Message: Error: Dart_SetBreakpoint: could not set breakpoint at line 4 in 'package:gtsi_web/endpoints.dart'

Any help appreciated.

Thanks.
