# getDisplayName abstract method

String getDisplayName([

1. Locale? locale

])

Returns the display name, optionally localized by `locale`.

Falls back to the English display name if no locale-specific version exists.

Example:

    final usd = Currency.getInstance('USD');
    print(usd.getDisplayName()); // US Dollar
    print(usd.getDisplayName(Locale('es', 'ES'))); // Dólar estadounidense
    print(usd.getDisplayName(Locale('zh', 'CN'))); // 美元

## Implementation

    String getDisplayName([Locale? locale]);
