stop method

Future<bool> stop(int exitCode, { String? reason, })

Stops the process.

Completes exitCode with exitCode and returns true, or returns false if the isolate had already finished (or another stop is in progress).

Implementation

Future<bool> stop(int exitCode, {String? reason}) async {
  if (_isolateCompleter.isCompleted || _stopping) {
    await _cancelSignalListeners();
    return false;
  }

  _stopping = true;

  await _cancelSignalListeners();

  // The isolate may have exited while the listeners were cancelled.
  if (_isolateCompleter.isCompleted) {
    return false;
  }

  final onStop = _onStop;
  if (onStop != null) {
    await onStop(reason ?? 'Terminated normally.');
  }

  if (stopByKill) {
    isolate.kill();
  }

  if (!_isolateCompleter.isCompleted) {
    _isolateCompleter.complete(exitCode);
  }

  return true;
}
