# Various Growth Standards implementation in Dart

## Example below

``` dart

import 'dart:convert';

import 'package:growth_standards/growth_standards.dart';

final birthDay = Date(year: 2022, month: Months.june, date: 30);

const weight = 12.1;

const length = 82;

const centimeters = Centimeters(length);

const kilograms = Kilograms(weight);

final age = Age.byDate(birthDay);

final gs = GrowthStandard.whoGrowthStandard;

final gsFromJson = gs.fromJson;

const sex = Sex.male;

void main() {

  print(

    'Age: ${age.yearsMonthsDaysOfAge.years} Years, ${age.yearsMonthsDaysOfAge.months} Months, ${age.yearsMonthsDaysOfAge.days} Days, with total ${age.ageInTotalMonthsByNow} in Months or ${age.ageInTotalDaysByNow} in Days',

  );

  // Demonstrating adjusted zscore calculation

  final calcLengthForAgeStanding = gs.lengthForAge(

    age: age,

    lengthHeight: centimeters,

    sex: sex,

    measure: LengthHeigthMeasurementPosition.standing,

  );

  print(calcLengthForAgeStanding.zScore(Precision.two));

  print(calcLengthForAgeStanding.percentile(Precision.two));
