valueAt method
Returns the runtime value at fieldIndex, applying decimal-null-as-zero
behavior when this context was configured for calculated-field evaluation.
Implementation
dynamic valueAt(int fieldIndex) {
final value = _values[fieldIndex];
if (value != null) {
return value;
}
if (_decimalNullAsZero && _fieldTypeAt(fieldIndex) == FdcDataType.decimal) {
return FdcDecimal.zero;
}
return null;
}
