deltaPct property

num? get deltaPct

Signed percent the measured value deviates from the golden ((measured − golden) / golden × 100, one decimal), null without a golden.

Implementation

num? get deltaPct {
  final g = golden;
  if (g == null || g == 0) return null;
  return double.parse(((measured - g) / g * 100).toStringAsFixed(1));
}
