chunked method

Iterable<List<T>> chunked(int size)

Splits the iterable into chunks of size.

[1,2,3,4,5].chunked(2) // [[1,2],[3,4],[5]]

Implementation

Iterable<List<T>> chunked(int size) sync* {
  assert(size > 0, 'chunk size must be > 0');
  var chunk = <T>[];
  for (final e in this) {
    chunk.add(e);
    if (chunk.length == size) {
      yield chunk;
      chunk = [];
    }
  }
  if (chunk.isNotEmpty) yield chunk;
}
