dispose method

Future<void> dispose()

Releases any internally-cached terminal. Call this when you're done issuing prompts (typically at the end of your program). No-op if the commander was constructed with an explicit terminal: argument.

Implementation

Future<void> dispose() async {
  if (_disposed) return;
  _disposed = true;

  final t = _cachedTerminal;
  _cachedTerminal = null;

  if (t != null) await t.shutdown();
}
