Steps to reproduce:

1. Plug in a device.
2. flutter create dummy
3. cd dummy/lib
4. flutter logs

Expected results:
Logs should start, probably not showing much unless you have a debug-mode Flutter app running already on the device.

Actual results:

No supported devices connected.

Works fine if you run it from a directory with a pubspec.yaml, but that command shouldn't need a Flutter package to find the devices on which logs are available.
