Support multiple devices

This is a feature request.

I would like to be able to work with 2 devices connected (linux desktop & emulator android mobile), and have both of them hot reloaded.
Is that possible?
Right now, I can open 2 devices, but I need to flutter.dev.detach, select another device, then flutter.attach and flutter.run, and it doesn't work always (device is slow to react, but I sometimes it cannot be reattached to).

I'm wondering if I misunderstood something. How are coc-flutter users doing when working on responsive layouts ?
