Flutter 颤振：如何从货币代码中获取货币符号

从语言代码来看，这很简单：

var format = NumberFormat.simpleCurrency(locale: "es");
print(format.currencySymbol);

但是我唯一拥有的是欧元，所以货币代码是var format=NumberFormat.simpleCurrency（locale:_language） 包装起作用

var format = NumberFormat.simpleCurrency(locale: _language); <-- doesn't really what matter what language you pass
print(format.simpleCurrencySymbol("EUR"));

import 'package:intl/intl.dart';

void currency() {
    Locale locale = Localizations.localeOf(context);
    var format = NumberFormat.simpleCurrency(locale: locale.toString());
    print("CURRENCY SYMBOL ${format.currencySymbol}"); // $
    print("CURRENCY NAME ${format.currencyName}"); // USD
}
