remove method

@override Future<Result<void, FileError>> remove(String path, { bool recursive = false, bool force = false, })

Removes a file or directory. With force, a missing path is not an error.

Implementation

@override
Future<Result<void, FileError>> remove(
  String path, {
  bool recursive = false,
  bool force = false,
}) async {
  final resolved = _normalize(path);
  final isFile = _files.containsKey(resolved);
  final isDir = _dirs.contains(resolved);
  if (!isFile && !isDir) {
    if (force) return const Ok(null);
    return Err(
      FileError(
        FileErrorCode.notFound,
        'No such file or directory',
        path: resolved,
      ),
    );
  }
  if (isFile) {
    _files.remove(resolved);
    return const Ok(null);
  }
  final prefix = '$resolved/';
  final hasChildren =
      _dirs.any((d) => d.startsWith(prefix)) ||
      _files.keys.any((f) => f.startsWith(prefix));
  if (hasChildren && !recursive) {
    return Err(
      FileError(FileErrorCode.invalid, 'Directory not empty', path: resolved),
    );
  }
  _dirs.removeWhere((d) => d == resolved || d.startsWith(prefix));
  _files.removeWhere((f, _) => f.startsWith(prefix));
  return const Ok(null);
}
