Group Separator

Numbers also use a group separator to help format large numbers by placing a separator every few digits. e.g. $100,000.00

In the English speaking world the comma (,) is used as the group separator however in large parts of the world the period (.) is used as the group separator.

Money2 use the English convention as default. To switch to the Euro style convention set the decimalSeparator and groupSeparator arguments when creating a currency.

You will also need to provide an appropriate pattern.

import 'package:money2/money2.dart';

   test('Group Separator', () {
      final euro = Currency.create('EUR', 2,
          symbol: '€',
          decimalSeparator: ',',
          groupSeparator: '.',
          pattern: 'S0,000.00');

      expect(euro.groupSeparator, equals('.'));
    });

Note: even if you have switched to alternate separators, Money2 patterns always use the '.' for a decimal separator and the ',' as the thousand group separator. This allows patterns to be shared amongst currencies.
