-- Autocommand: trigger Flutter hot reload on save
--
-- This runs whenever you save a *.dart file (BufWritePost).
-- It checks if a tmux session named "flutter" exists.
-- If it does, it sends the keys "r<Enter>" to the "app" window
-- of that session, which tells `flutter run` to hot-reload.
--
-- Workflow:
--   1. Start tmux:   tmux new -s flutter -n app
--   2. Inside tmux "app" window, run: flutter run
--   3. Open another window/pane for nvim.
--   4. Whenever you :w a Dart file in nvim, hot reload will fire.
