Implementation

static String? word(int n) {
  if (n.toString().length >= 10) {
    return null;
  }
  if (n == 0) {
    return 'zero';
  }
  var adder = '';
  if (n < 0) {
    adder = 'negative ';
    n *= -1;
  }
  var output = '';

  output += _numberToWords((n / 10000000).floor(), 'crore ');
  output += _numberToWords(((n / 100000).floor() % 100), 'lakh ');
  output += _numberToWords(((n / 1000).floor() % 100), 'thousand ');
  output += _numberToWords(((n / 100).floor() % 10), 'hundred ');
  if (n > 100 && (n % 100) != 0) {
    output += 'and ';
  }
  output += _numberToWords((n % 100), '');
  return adder + output;
