AppSignal enum

A termination request delivered to the app, in platform-neutral terms.

On POSIX these map from SIGINT / SIGTERM / SIGHUP; a remote host may synthesize them (e.g. a server shutting a session down). Kept free of dart:io types so non-POSIX drivers can emit them too.

Values

interrupt → const AppSignal

Interactive interrupt — SIGINT (kill -INT). Note the in-terminal Ctrl+C keypress arrives as a KeyEvent in raw mode, not as a signal.

terminate → const AppSignal

Termination request — SIGTERM (supervisors, kill, service managers).

hangup → const AppSignal

Terminal hangup — SIGHUP: the controlling terminal went away (window closed, SSH session dropped). The terminal cannot be restored, but the app's own cleanup — state saved, children stopped, logs flushed — still runs through the normal exit path.
