How do I split or chunk a list into equal parts, with Dart?

by

Here is another way:

  var chunks = [];
  int chunkSize = 2;
  for (var i = 0; i < letters.length; i += chunkSize) {
    chunks.add(letters.sublist(i, i+chunkSize > letters.length ? letters.length : i + chunkSize)); 
  }
  return chunks;

Run it on dartpad
