toRepresentationString method

String toRepresentationString({ PaymentAmountStringOptions options = const PaymentAmountStringOptions(), })

Returns the amount you would see displayed (e.g. EUR 0.25)

Implementation

String toRepresentationString(
    {PaymentAmountStringOptions options =
        const PaymentAmountStringOptions()}) {
  String wholes, somes;
  var negative = value < 0;
  var integer = (negative ? -value : value).toString();
  if (exponent <= 0) {
    wholes = integer + ''.padRight(-exponent, '0');
    somes = '';
  } else if (integer.length <= exponent) {
    wholes = '0';
    somes = integer.padLeft(exponent, '0');
  } else {
    wholes = integer.substring(0, integer.length - exponent);
    somes = integer.substring(integer.length - exponent);
  }
  var paddedWholes = wholes.padLeft(options.padIntegers, ' ');
  var paddedSomes = somes.padRight(options.padFractions, '0');
  var currencyString = options.currency ? currency + ' ' : '';
  return (currencyString +
      (negative ? '-' : '') +
      paddedWholes +
      (paddedSomes == '' ? '' : '.' + paddedSomes));
}
