# getSymbol abstract method

String getSymbol([

1. Locale? locale

])

Returns the currency symbol, optionally localized by `locale`.

Falls back to the default symbol if no locale-specific version exists.

Example:

    final usd = Currency.getInstance('USD');
    print(usd.getSymbol()); // $
    print(usd.getSymbol(Locale('es', 'MX'))); // US$
    print(usd.getSymbol(Locale('zh', 'CN'))); // 美元

## Implementation

    String getSymbol([Locale? locale]);
