Lock files are stored in a parallel directory structure:

• Data: ./WorkDB/collection/item
• Lock: ./WorkDBLocks/collection/item.lock

Usage

final lockManager = LockManagerSync(fileSystem);

if (lockManager.tryAcquireSync('users/user-1')) {
  try {
    // perform operation
  } finally {
    lockManager.releaseSync('users/user-1');
  }
}
