Nourhan Hasan 596e0b0849 [vm/service]: expose Pointer<T> address in VM Service Protocol
Pointer<T> instances were previously serialized as PlainInstance
with no address, making them opaque to all debugger clients.

Observatory Developer Tooling

WARNING: This tooling is deprecated and maintained on a best-effort basis by members of the Dart VM team.

Activating Observatory

To easily serve Observatory without having to manually run webdev serve in this project, Observatory can be activated as a global pub package and run via the observatory tool.

To do this, run dart bin/activate.dart, which will create the observatory script at $PUB_CACHE/bin.

Note: If any changes are made to bin/observatory.dart, dart bin/activate.dart must be re-run to pick up the changes.

Serving Observatory

To serve Observatory, simply run the observatory command. To automatically launch Observatory in Chrome, provide the --launch flag.

Developing Observatory

When making changes to Observatory, run observatory --debug to run Observatory with DDC. This will allow for a more typical web development workflow as changes to the Observatory sources will be picked up automatically on a page refresh.

Code Reviews

The development workflow of Dart (and Observatory) is based on code reviews.

Follow the code review instructions to be able to successfully submit your code.
