clampMagnitude method

Velocity clampMagnitude (double minValue, double maxValue)

Return a velocity whose magnitude has been clamped to minValue and maxValue.

If the magnitude of this Velocity is less than minValue then return a new Velocity with the same direction and with magnitude minValue. Similarly, if the magnitude of this Velocity is greater than maxValue then return a new Velocity with the same direction and magnitude maxValue.

If the magnitude of this Velocity is within the specified bounds then just return this.

Implementation 

Velocity clampMagnitude(double minValue, double maxValue) {
  assert(minValue != null && minValue >= 0.0);
  assert(maxValue != null && maxValue >= 0.0 && maxValue >= minValue);
  final double valueSquared = pixelsPerSecond.distanceSquared;
  if (valueSquared > maxValue * maxValue)
    return Velocity(pixelsPerSecond: (pixelsPerSecond / pixelsPerSecond.distance) * maxValue);
  if (valueSquared < minValue * minValue)
    return Velocity(pixelsPerSecond: (pixelsPerSecond / pixelsPerSecond.distance) * minValue);
  return this;
}
