- Provide a new callback to Dart_Initialize that will be called when the service isolate needs the Observatory assets
- Move asset management code out of embedder and into common dart:_vmservice
- Use the tar format as the archive format
- Add build script to generate .cc file containing the archive
- Add a simple tar parser to service isolate
This makes it possible for embedders to not bake Observatory into their executable but instead load it off disk or over the network. The standalone embedder still links Observatory into the executable.
