scaleTo method

void scaleTo(
  1. double newLength
)

Changes the length of the vector to the length provided, without changing direction.

If you try to scale the zero (empty) vector, it will remain unchanged, and no error will be thrown.

Implementation

void scaleTo(double newLength) {
  final l = length;
  if (l != 0) {
    scale(newLength.abs() / l);
  }
}
