Migration Guide

From 1.x to 2.0

Currency Configuration:

// Old
converter.convert(amount, mainUnit: 'dollar', subUnit: 'cent');

// New
converter.convert(amount, currency: CurrencyConfig.usDollar);

Custom Currencies:

// Old
// Not supported in 1.x

// New
final customCurrency = CurrencyConfig(
  mainUnits: {
    Language.en: 'token',
    Language.fa: 'ژتون',
  },
  subUnits: {
    Language.en: 'bit',
    Language.fa: 'بیت',
  },
);

Pluralization:

// Old - Manual handling
final unit = amount == 1 ? 'dollar' : 'dollars';

// New - Automatic
final unit = currency.getMainUnit(Language.en, count: amount);
