You just write something like this: double average (Float32x4List list) { var n = list.length; var sum = new Float32x4.zero(); for (int i = 0; i < n; i++) { sum += list[i]; } var total = sum.x + sum.y + sum.z + sum.w; return total / (n * 4); } Instead of: double average (Float32List list) { var n = list.length; var sum = 0.0; for (int i = 0; i < n; i++) { sum += list[i]; } return sum / n; }
