An update for above answers:

First add intl package into your pubspec.yaml file, just after flutter sdk (like below):

    dependencies:
      flutter:
        sdk: flutter
      intl: ^0.16.0

If you use flutter_localizations, intl must be above of that.

Now you can use NumberFormat class.

Some examples:

print(NumberFormat.currency().format(123456)); // USD123,456.00

print(NumberFormat.currency(locale: 'eu').format(123456)); // 123.456,00 EUR

print(NumberFormat.currency(name: 'EURO').format(123456)); // EURO123,456.00

print(NumberFormat.currency(locale: 'eu', symbol: '?').format(123456)); // 123.456,00 ?

print(NumberFormat.currency(locale: 'eu', decimalDigits: 3).format(123456)); // 123.456,000 EUR

print(NumberFormat.currency(locale: 'eu', customPattern: '\u00a4 #,##.#').format(123456)); // EUR 12.34.56,00
