See the dev services started by makedeck with live logs, open any of them in Terminal (e.g. to press r for Flutter hot reload), restart or stop them.
This extension shows sessions created by the makedeck launcher, so you need both:
tmux: brew install tmux
The launcher from the makedeck repository:
git clone https://github.com/Lorenzo-Se/makedeck.git
ln -s "$PWD/makedeck/bin/makedeck" "$(brew --prefix)/bin/makedeck"
Then run makedeck in a project root. It starts every prerequisite of the Makefile's dev target in its own background tmux window. Open Dev Services in Raycast to see them.
How to structure the Makefile is described in the makedeck README.
