Correct Answer

I got a correct answer use jiffy package.

import 'package:jiffy/jiffy.dart';

then use this code

vehicleAge(DateTime doPurchase, DateTime doRenewel) {
    var dt1 = Jiffy(doPurchase);
    var dt2 = Jiffy(doRenewel);

    int years = int.parse("${dt2.diff(dt1, Units.YEAR)}");
    dt1.add(years: years);

    int month = int.parse("${dt2.diff(dt1, Units.MONTH)}");
    dt1.add(months: month);

    var days = dt2.diff(dt1, Units.DAY);

    
    return "$years Years $month Month $days Days";
    
  }

Use this package time_machine and try this code

 vehicleAge(DateTime doPurchase, DateTime doRenewel) {

  LocalDate a = LocalDate.dateTime(doPurchase);
  LocalDate b = LocalDate.dateTime(doRenewel);
  
  Period diff = b.periodSince(a);
  return "${diff.years} Years ${diff.months} Months ${diff.days} Days";
}

Try with this

 vehicleAge(DateTime doPurchase, DateTime doRenewel) {
    Duration parse = doPurchase.difference(doRenewel).abs();
    return "${parse.inDays~/360} Years ${((parse.inDays%360)~/30)} Month ${(parse.inDays%360)%30} Days";
  }
