Dart directory scan and list population

I'm new to this dart stuff and having problems with creating a list with file names from a directory. The example code makes sense but doesn't work and provides no error messages.

I'm really not enjoying how Dart complicates simple tasks.

var flist = new List();
Process.run('cmd', ['/c', 'dir *.txt /b']).then((ProcessResult results) {
 flist.add(results.toString());
});

i know it's way off.. how do i go about this without having to call any outside voids.. i'd like to keep my code in the 'main' function.

You might find this answer useful. It shows how to use the Directory object to list contents of a directory: How do I list the contents of a directory with Dart?

Looks like you're trying to find all files in a directory that end in *.txt. You could do this:

import 'dart:io';

main() {
  var dir = new Directory('some directory');
  var contents = dir.listSync();
  var textFiles = contents.filter((f) => f.name.endsWith('.txt'));
}
