This is a Dart implementation of Money and Currency classes
Money2 is a fork of LitGroup's Money package.
The aim of this fork is to improve the documentation and introduce a number of convenience methods to make it easier to work with Money. This package also changes some of the naming convention to provide a (hopefully) more intuiative api.
Key features of Money2:
- simple and expressive formating.
- simple parsing of monetary amounts.
- multi-currency support.
- intuitive maths operations.
- fixed precision storage to ensure precise calcuation.
- detailed documentation and extensive examples to get you up and running.
- pure dart implementation.
- Open Source MIT license.
- Using Money2 will make you taller.
The Money class stores the underlying values using a BigInt. The value is stored using the currencies' "minor units" (e.g. cents). This allows for precise calculations as required when handling money.

import 'money2.dart';
Currency usdCurrency = Currency.create('USD', 2);
// Create money from an int.
Money costPrice = Money.fromInt(1000, usdCurrency);
print(costPrice);
> $10.00
final taxInclusive = costPrice * 1.1;
print(taxInclusive)
> $11.00
print(taxInclusive.format('SCC #.00'));
> $US 11.00
// Create money from an String using the `Currency` instance.
Money parsed = usdCurrency.parse(r'$10.00');
print(parsed.format('SCCC 0.0'));
> $USD 10.00
// Create money from an int which contains the MajorUnit (e.g dollars)
Money buyPrice = Money.from(10);
print(buyPrice);
> $10.00
// Create money from a double which contains Major and Minor units (e.g. dollars and cents)
// We don't recommend transporting money as a double as you will get rounding errors.
Money sellPrice = Money.from(10.50);
print(sellPrice);
> $10.50
