string_converter

String type converter for Dart

• UTF8 <-> UTF16
• UTF8 <-> UTF32

Getting Started

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  string_converter:

Next we need to install this

# Dart
pub get

# Flutter
flutter packages get

In your library add the following import:

import 'package:string_converter/converter.dart';

Usage

void main() {
  final converter = StringConverter();
  String text = "Hello";

  // Convert utf8 to utf16
  String utf16 = converter.toUTF16(text);
  // \u0048\u0065\u006c\u006c\u006f

  // Convert utf8 to utf32
  String utf32 = converter.toUTF32(text);
  // u+00000048u+00000065u+0000006cu+0000006cu+0000006f

  // Convert utf16 to utf8
  String utf8 = converter.toUTF8(utf16);
  // Hello
}

You can use the extension method directly on the string too

print("hello".toUTF16());
// print \u0048\u0065\u006c\u006c\u006f

You can remove \u & u+ using the args remove

print(utf8.toUTF16(remove: true));
// print 0048 0065 006c 006c 006f

print(utf8.toUTF32(remove: true));
// print 00000048 00000065 0000006c 0000006c 0000006f
