如何在 Flutter 中将数字格式化为货币字符串

Question

***大家好，如何将下面的代码转换为货币 Dart/Flutter？

flutter中有一个名为number format的类，但我不太明白。你能帮忙解决这个问题吗？ 示例“$ 3,500.00”***

 @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      crossAxisAlignment: CrossAxisAlignment.center,
      children: [
        Text(
          "Toplam Masraf: ",
          style: TextStyle(
              color: Colors.orange.shade500,
              fontSize: 15,
              fontWeight: FontWeight.w600),
        ),
        Text(
          
            toplam >= 0 ? "${toplam.toStringAsFixed(2)}" : "0.00".toString(),
          
          style: TextStyle(
              color: Colors.orange.shade900,
              fontSize: 20,
              fontWeight: FontWeight.w800),
    ),
        Text(
          "₺",
          style: TextStyle(
              color: Colors.orange.shade900,
              fontSize: 25,
              fontWeight: FontWeight.w800),
        )
      ],
    );
  }
