Money and Currency value objects for Dart

A Money is a value object that represents an amount and an associated currency. Amounts either represent a real value (e.g. -$1927.10, ￥10, £1.56, 0.00kr.) or are unavailable (e.g. have no numerical value).

☞ In many financial applications, host systems can be unavailable throughout the day due to batch jobs running etc, and for this reason, amounts have notion of being unavailable.

This library is open source (BSD-2). Development occurs on GitHub. Package is hosted on dart packages.
