close method

Future<void> close()

Flushes pending writes and releases the file handle. Idempotent: safe to call more than once (e.g. from a finally plus an error path); the second and later calls are no-ops.

Implementation

Future<void> close() async {
  if (_closed) return;
  _closed = true;
  await _raf.flush();
  await _raf.close();
}
