StringBuilder SetNth

Demonstrates the SetNth method. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // The SetNth method is handy for setting a part of a delimited string.
  // For example:

  final sb = CkStringBuilder();
  sb.append('red,blue,"green,purple",,yellow');

  final delimiterChar = ',';
  final exceptDoubleQuoted = true;
  final exceptEscaped = true;

  sb.setNth(2, 'magenta', delimiterChar, exceptDoubleQuoted, exceptEscaped);
  // Prints "red,blue,magenta,,yellow"
  print(sb.getAsString());

  sb.setNth(3, 'orange', delimiterChar, exceptDoubleQuoted, exceptEscaped);
  // Prints "red,blue,magenta,orange,yellow"
  print(sb.getAsString());

  // What happens if we start with an empty string?
  sb.clear();

  sb.setNth(2, 'apple', delimiterChar, exceptDoubleQuoted, exceptEscaped);
  // Prints ",,apple"
  print(sb.getAsString());

  sb.setNth(0, 'orange', delimiterChar, exceptDoubleQuoted, exceptEscaped);
  // Prints "orange,,apple"
  print(sb.getAsString());

  sb.setNth(1, 'banana', delimiterChar, exceptDoubleQuoted, exceptEscaped);
  // Prints "orange,banana,apple"
  print(sb.getAsString());
