tipValueOfPercentage property
This should be a non-null value if tipIndicator is TipIndicator.tipValuePercentage
Expected range is 00.01 to 99.99 (in percentage)
Implementation
late final double? tipValueOfPercentage = () {
final data = this[57];
if (data != null) {
return double.tryParse(data,);
}
return null;
}();
