使用dart将年数转换为日期

import 'dart:core';

DateTime convertYearsToDate(int years) {
  DateTime currentDate = DateTime.now();
  int currentYear = currentDate.year;
  int targetYear = currentYear - years;
  
  DateTime targetDate = DateTime(targetYear, currentDate.month, currentDate.day);
  return targetDate;
}

void main() {
  int years = 5;
  DateTime result = convertYearsToDate(years);
  print("转换后的日期为：${result.year}-${result.month}-${result.day}");
}
