Platform compatibility

This package is compatible with all Flutter platforms. However, CurrencyFormatter().getLocal() does not work for web.

Format money

To set how a double will be formatted, create a CurrencyFormatterSettings:

CurrencyFormatterSettings euroSettings = CurrencyFormatterSettings(
  symbol:'€',
  symbolSide: SymbolSide.left,
  thousandSeparator: '.',
  decimalSeparator: ',',
);

symbolSide can be set to SymbolSide.left, SymbolSide.right, or SymbolSide.none. thousandSeparator and decimalSeparator default to '.', ',' or ',','.' automatically depending on symbolSide.

To format a num, CurrencyFormatter().format() is used:

CurrencyFormatter cf = CurrencyFormatter();
num amount = 1910.9347;
String formatted = cf.format(amount, euroSettings); // 1.910,93 €
String compact = cf.format(amount, euroSettings, compact: true); // 1,91K €
String threeDecimal = cf.format(amount, euroSettings, decimal: 3); // 1.910,945 €

Parse formatted money

To get a num from a formatted String, use CurrencyFormatter().format():

// Above's example continuation
num parseFormatted = cf.parse(formatted, euroSettings); // 1910.93
num parseCompact = cf.parse(compact, euroSettings); // 1910.0
num parseThreeDecimal = cf.parse(threeDecimal, euroSettings); // 1910.935

Predefined CurrencyFormatterSettings

Predefined settings for many currencies are also included in this package. They are listed in the CurrencyFormatter.majors variable and their symbols in CurrencyFormatter.majorSymbols. They can be used in both of the following ways which do exactly the same:

String inUSD = cf.format(amount, CurrencyFormatter.usd); // $ 1,910.93
String inRUB = cf.format(amount, cf.majors['rub']!); // 1.910,93 ₽

String jpySymbol = cf.majorSymbols['jpy']!; // ¥

In Flutter, you can get the default CurrencyFormatterSettings according to the device language using cf.getLocal():

String inSystemCurrency = cf.format(amount, cf.getLocal() ?? cf.majors['usd']!);

You can get a CurrencyFormatterSettings from a currency symbol (if it is in CurrencyFormatter.majors) with CurrencyFormatter.getFromSymbol():

String fromSymbol = cf.format(amount, cf.getFromSymbol('£')!); // £ 1,910.35
