scale static method

double scale(num value, { required num fromMin, required num fromMax, required num toMin, required num toMax, })

Re-maps value from one range to another.

Number.scale(0.5, fromMin: 0, fromMax: 1, toMin: 0, toMax: 100); // 50

Implementation

static double scale(
  num value, {
  required num fromMin,
  required num fromMax,
  required num toMin,
  required num toMax,
}) {
  final fromRange = fromMax - fromMin;
  if (fromRange == 0) return toMin.toDouble();
  return toMin + (value - fromMin) * (toMax - toMin) / fromRange;
}
