shutdownSharedStdinOnExit property
Whether to shut down the shared stdin broadcast stream on exit.
The TUI uses a shared broadcast wrapper around stdin so it can pause and
resume input listening during a single run (e.g. suspend/exec) without
hitting Dart's single-subscription stdin limitation.
When enabled, program shutdown cancels the underlying stdin subscription so the process can exit cleanly on real TTYs.
Implementation
final bool shutdownSharedStdinOnExit;
