dispose method

Future<void> dispose()

Releases the worker's engine and store and stops its isolate.

Implementation

Future<void> dispose() async {
  if (_disposed) return;
  try {
    await _request('dispose').timeout(const Duration(seconds: 5));
  } on Object {
    // A worker that cannot answer is about to be killed anyway.
  }
  _disposed = true;
  _failPending('the worker was released');
  _responses.close();
  _isolate.kill(priority: Isolate.immediate);
}
