Changelog #

0.5.0 #

• Change [codeUnits] getter to [utf16CodeUnits] which returns an iterable. This avoids leaking that the underlying string has efficient UTF-16 code unit access in the API, and allows the same interface to be just as efficiently implemented on top of UTF-8.

0.4.0 #

• Added an extension method on String to allow easy access to the Characters of the string:

  print('The first character is: ' + myString.characters.first)
  

• Updated Dart SDK dependency to Dart 2.6.0

0.3.1 #

• Added small example in example/main.dart
• Enabled pedantic lints and updated code to resolve issues.

0.3.0 #

• Updated API which does not expose the underlying string indices.

0.1.0 #

• Initial release

example/main.dart

import 'package:characters/characters.dart';

// Small API examples. For full API docs see:
// https://pub.dev/documentation/characters/latest/characters/characters-library.html
main() {
  String hi = 'Hi 🇩🇰';
  print('String is "$hi"\n');

  // Length.
  print('String.length: ${hi.length}');
  print('Characters.length: ${hi.characters.length}\n');

  // Last character.
  print('The string ends with: ${hi.substring(hi.length - 1)}');
  print('The last character: ${hi.characters.last}\n');

  // Skip last character.
  print('Substring -1: "${hi.substring(0, hi.length - 1)}"');
  print('Skipping last character: "${hi.characters.skipLast(1)}"\n');

  // Replace characters.
  Characters newHi =
      hi.characters.replaceAll('🇩🇰'.characters, '🇺🇸'.characters);
  print('Change flag: "$newHi"');
