String ratio(

  3. int decimal = 4,
})

Implementation

static String ratio(
    String? value1,
    String? value2, {
      int decimal = 4,
    }) {
  final v1 = double.tryParse(value1 ?? '');
  final v2 = double.tryParse(value2 ?? '');

  if (v1 == null || v2 == null || v2 == 0) return '';

  final result = v1 / v2;

  return format(result.toString(), decimal: decimal);
}
