This would be useful for things like mocking when testing.

Just a tracking issue, so I know when I can start using it from there.

abstract class HtmlFileSystemEntry implements FileSystemEntry {
  HtmlFileSystemEntry._(this._fs, this._path);
}

This class is an abstract class.
This class is a public class.
This class with a private constructor.

Public abstract class with a private constructor.

How can be called such programming techniques?

This technique only useful for the static classes.

Eg.

abstract class Platform {
  Platform._internal();

  static final int foo = 0;
}

This class is an abstract class (cannot be instantiated).
This class is a public class (cannot be used anywhere).
This class with a private constructor (cannot be instantiated).

What wrong with this approach?

abstract class HtmlFileSystemEntry implements FileSystemEntry {
}

class _HtmlFileSystemEntry implements HtmlFileSystemEntry {
  _HtmlFileSystemEntry(this._fs, this._path);
}

Of cource, if you really need HtmlFileSystemEntry interface.

P.S.

I know that you (possible) like a Dartish way.
But Dartish way (beloved by ahe) are not a right way for the many serious programmers.

This is because, if your HtmlFileSystemEntry is an interface purpose type then it has a wrong design.

abstract class HtmlFileSystemEntry implements FileSystemEntry {
  final HtmlFileSystem _fs;
  final String _path;

  HtmlFileSystemEntry._(this._fs, this._path);

  String get path => _path;
}

Remeber: I cannot use it as an interface.

// Missing concrete implementation 
// of getter 'HtmlFileSystemEntry._path',
// getter 'HtmlFileSystemEntry._fs'
// getter 'HtmlFileSystemEntry.path'
class MyHtmlFileSystemEntry implements HtmlFileSystemEntry {
}

If I cannot use it as an interface then why it is a

• Public
• Abstract
• Has a private constructor

Where is a logic?
