containsSync method
      
bool
containsSync(
    
- FileSystemEntity entity, {
- bool recursive = false,
- FileSystemEntityPathComparator identical = FileSystemEntity.identicalSync,
Checks if this directory contains the entity.
The entity can be a File or a Directory.
If recursive is true, it checks the subdirectories too.
Returns a bool.

Implementation
bool containsSync(
  FileSystemEntity entity, {
  bool recursive = false,
  FileSystemEntityPathComparator identical = FileSystemEntity.identicalSync,
}) {
  final entities = listSync(recursive: recursive);
  return entities.any((element) => identical(entity.path, element.path));
}
