The passed amount must match the given pattern or if no pattern is supplied the the default pattern of the currency indicated by the currency. The S and C characters in the pattern are optional.

See format for details on how to construct a pattern.

Throws an MoneyParseException if the amount doesn't match the pattern.

If the number of decimals in amount exceeds the Currency's decimalDigits then excess digits will be ignored.

currency - the currency of the amount.

Implementation

factory Money.parseWithCurrency(String amount, Currency currency,
    {String? pattern, int? decimalDigits}) {
  if (amount.isEmpty) {
    throw MoneyParseException('Empty amount passed.');
  }

  try {
    pattern ??= currency.pattern;

    final decoder = PatternDecoder(currency, pattern);

    final data = decoder.decode(amount);

    return Money._from(
        Fixed.copyWith(data.amount,
            scale: decimalDigits ?? currency.decimalDigits),
        currency);
    // ignore: avoid_catches_without_on_clauses
  } catch (e) {
    throw MoneyParseException(e.toString());
  }
