You can follow:

  1. Import package: INTL

import 'package:intl/intl.dart';

  1. Create method
String formatNumber(int number) {
  var formatter = NumberFormat("##,##,##,##0.00", "en_IN");
  if (number >= 10000000) {
    return formatter.format(number / 10000000) + " cr";
  } else if (number >= 100000) {
    return formatter.format(number / 100000) + " lac";
  } else {
    return formatter.format(number);
  }
}
  1. Call the method:
  print(formatNumber(164023)); // 1.64 lac
  print(formatNumber(23412456)); // 2.34 cr

Have a nice day...

String convertNumberToWords(int number) {
  if (number >= 10000000) {
    return "${(number/10000000).toStringAsFixed(2)} cr";
  } else if (number >= 100000) {
    return "${(number/100000).toStringAsFixed(2)} lac";
  }
  return number.toString();
}

Userstanding :

#convertNumberToWords function takes in an integer number and returns a string that represents the number in words. If the number is greater than or equal to 10 million, the function returns the number divided by 10 million with two decimal places, followed by the string "cr".

If the number is greater than or equal to 100,000, the function returns the number divided by 100,000 with two decimal places, followed by the string "lac". If the number is less than 100,000, the function returns the number as a string.
