Flutter 生成指定的位置的0

  double genDigits(double d) {
    var i = d.round();
    var length = i.toString().length;
    final fixedLengthList =
        List<int>.generate(length-2, (int index) => 0, growable: false);
    var tmpNum = double.parse("1${fixedLengthList.join("")}");
    return tmpNum;
  }

void main() {
  print(genDigits(112));  // 10
}
