dispose method

@override Future<void> dispose()

SIGTERM, 2s grace, SIGKILL, then deletes the temp script directory. Idempotent.

Implementation

@override
Future<void> dispose() async {
  final process = _process;
  _process = null;
  _bridges = null;
  _disposed = true;
  await _stop(process);
  final dir = _tempDir;
  _tempDir = null;
  await _deleteTempDir(dir);
}
