Research direction

The issue names PM2's --wait-ready entry point, Dart, and Node's process.send('ready'), but no source file or test. Start by tracing how PM2 handles the ready signal for non-Node processes. Done means determining and documenting a supported way for a Dart server to signal readiness without the Node.js wrapper.

Description

I have a web server in dart which takes some time to start. How do i call process.send('ready') from the dart program ?

Currently I am using a workaround of running a nodejs file which is a wrapper to run the dart server and calling process.send from there. Is there any better way of doing this ?
