toList method Null safety

List<E> toList (
  1. {bool growable: true}
)
override

Creates a List containing the elements of this Iterable.

The elements are in iteration order. The list is fixed-length if growable is false.

Implementation

List<E> toList({bool growable = true}) {
  if (this.isEmpty) return List<E>.empty(growable: growable);
  var first = this[0];
  var result = List<E>.filled(this.length, first, growable: growable);
  for (int i = 1; i < this.length; i++) {
    result[i] = this[i];
  }
  return result;
}
