sub method Null safety

void sub(
  1. int index,
  2. Vector4 vector
)

Substract vector from the vector at index.

Implementation

void sub(int index, Vector4 vector) {
  final i = _vectorIndexToBufferIndex(index);
  final storage = vector.storage;
  buffer[i + 0] -= storage[0];
  buffer[i + 1] -= storage[1];
  buffer[i + 2] -= storage[2];
  buffer[i + 3] -= storage[3];
}
