import 'package:heartinz_essentials/heartinz_essentials.dart';

void main() {
  // Create an instance of Essentials
  final essentials = Essentials();

  // Example 1: Grand Total Calculation
  // GrandTotalModel grandTotal = essentials.calc.calculateGrandTotal(
  //   totalMrp: essentials.currency.toSubunit(0.5, "INR"),
  //   totalSalePrice: essentials.currency.toSubunit(0.245, "INR"),
  //   totalBasePrice: essentials.currency.toSubunit(1, "INR"),
  //   totalTaxAmount: 18,
  // );
  // print('/// GRAND TOTAL /// \n ${grandTotal.toMap()}');

  // Example 2: Convert to Currency
  // double currencyValue = essentials.currency.toCurrency(1500, 'USD');
  // print('/// CONVERT TO CURRENCY /// \n  $currencyValue');

  // Example 3: Convert to Subunits
  // int subunitValue = essentials.currency.toSubunit(1500.75, 'USD');
  // print('/// CONVERT TO SUBUNITS /// \n  $subunitValue');

  // Example 4: GST Calculation
  GSTResult gstDetails = essentials.calc.gstCalculate(
    mrp: essentials.currency.toSubunit(200, "INR"),
    salePrice: essentials.currency.toSubunit(150, "INR"),
    basePrice: essentials.currency.toSubunit(0, "INR"),
    taxPercent: 18,
    quantity: 99999999.001,
    lock: "SALEPRICE",
  );
  print('/// GST DETAILS /// \n ${gstDetails.toJson()}');

  // Example 5: Date and Time Operations - ISO to Display Format
  // String isoString = "2024-12-16T15:30:00Z";
  // var displayTime = essentials.date.displayIso(isoString);
  // print('/// DISPLAY IN ISO /// \n $displayTime');

  // Example 6: Split ISO String
  // var isoSplit = essentials.date.splitIso(isoString);
  // print('/// SPLIT ISO /// \n  $isoSplit');

  // Example 7: Convert to Target Time Zone
  // String targetTimeZone = "Asia/Kolkata";
  // var timeInTargetZone = essentials.date.toTimeZone(isoString, targetTimeZone);
  // print(
  //     '/// CONVERT TO TARGET TIME ZONE /// \n $targetTimeZone: $timeInTargetZone');

  // Example 8: Current Time by Time Zone
  // var currentTime = essentials.date.getCurrentTimeByTimeZone("Asia/Kolkata");
  // print('/// CURRENT TIME BY TIME ZONE /// \n  $currentTime');

  // Example 9: Day Boundaries in UTC
  // String isoDateStr = "2024-12-16T15:30:00Z";
  // var dayBoundaries = essentials.date.dayBoundariesInUTC(isoDateStr);
  // print('/// DAY BOUNDRIES /// \n  $dayBoundaries');

  // Example 10: Time Difference Between Two Dates
  // var timeDifference = essentials.date.timeDifference(
  //     "2024-12-16T15:30:00Z", "2024-12-17T16:30:00Z");
  // print('/// TIME DIFFERENCE /// \n $timeDifference');

  // Example 11: Modify ISO Time by Duration
  // String modifiedIsoTime =
  //     essentials.date.modifyIso(isoString, Duration(hours: 2));
  // print('/// MODIFY ISO TIME BY DURATION /// \n  $modifiedIsoTime');

  // Example 12: Convert Date to ISO Format
  // String dateStr = "2024-12-16";
  // String type = "MM-dd-yyyy";
  // String timeZone = "Asia/Kolkata";
  // String isoFormat = essentials.date.toIso(
  //     dateStr: dateStr, type: type, timeZone: timeZone);
  // print('/// TO ISO FORMAT /// \n $isoFormat');

  // Example 13: Convert to UTC
  // var utcTime = essentials.date.toUtc(isoString);
  // print('/// TO UTC /// \n $utcTime');
