Unable to figure out how to resume a Dart process that has been paused on isolate start/end

[a-siva]

When I start a dart process with the --observe option, I see the following message on my console

vm-service: isolate(1724937471817639) 'main' has no debugger attached and is paused at exit. Connect to the Dart VM service at http://127.0.0.1:37863/xyAvpbmSkDM=/ to debug.

I connect to http://127.0.0.1:37863/xyAvpbmSkDM=/ using my browser and it brings up devtools. Once here I don't see anyway to resume
the process. I searched under VM Tools and did not find any way of resuming the process there too.
There used to be a debugger tab in the past from where it was possible to issue the continue command but this does not seem to exist anymore.

How are you running your Dart app? I cannot reproduce by running dart --observe run foo.dart and then opening the DevTools link.

Sorry for the late response on the reproduction instructions.

I was working on a debug build of the dart sdk when I ran into this problem, maybe this is not an issue for the end users.
Here is the list of steps for reproducing.

1. build a debug version of the dart sdk using tools/build.py create_sdk
2. build an aot snapshot as follows dart compile aot-snapshot -o /tmp/hello.aot /tmp/hello.dart
3. run the generated aot snapshot as follows out/DebugX64/dart-sdk/bin/aotsnapshot --observe /tmp/hello.aot
4. Now connect to url printed above and that launches devtools which does not have the debugger tab

I feel a similar reproduction should be possible with the flutter profile build.

Contents of /tmp/hello.dart

import 'dart:io';

main() {
  for (int i = 0; i < 500; i++) {
    print('Hello World!');
    sleep(Duration(seconds: 1));
  }
}
