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

Question

Assume I have a list like:

var letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'];

I would like a list of lists of 2 elements each:

var chunks = [['a', 'b'], ['c', 'd'], ['e', 'f'], ['g', 'h']];

What's a good way to do this with Dart?

Answer 1

Here is another way:

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