用阿拉伯格式的飞镖显示数字

Question

如何在Flutter应用中以阿拉伯格式显示数字？

不是将数字显示为1,2,3，而是将它们显示为١、٢、٣

我尝试使用NumberFormat类，但是它不起作用。

            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              new Text(NumberFormat().format(1)),
              new Text(NumberFormat().format(2)),
              new Text(NumberFormat().format(3)),
            ],
          ),

Answer 3

String convertToArabicNumber(String number) {
  String res = '';

  final arabics = ['٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩'];
  number.characters.forEach((element) {
     res += arabics[int.parse(element)];
  });

/*   final latins = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']; */
  return res;
}
