This library provides these functions for Turkish language:

  • Converting strings to lower, upper and title case.
  • Regular and ignore case string sorting.

Casing operations does not work correctly in Dart core libraries because Dart uses default unicode mappings. Default case mappings fails for Turkish i->İ and I->ı conversions.

This library may not be necessary for Flutter or web projects if they use underlying system methods for locale specific text operations. But it can be handy when that is not the case.

Current implementation does not handle two code-unit variations. Complete special casing rules are defined here.


Add this line to pubspec.yaml:

turkish: '>=0.1.0'

Add this line to the import section:

import 'package:turkish/turkish'

There is a single object instance exposed from library called turkish. All operations are accessed through this object.

Usage Example:

import 'package:turkish/turkish';
var inputL = "kısa şiir";
print("UpperCase for [$inputL]");
print("Default= ${inputL.toUpperCase()}, Turkish=${turkish.toUpperCase(inputL)}\n");

var inputU = "KISA ŞİİR";
print("LowerCase for [$inputU]");
print("Default= ${inputU.toLowerCase()}, Turkish=${turkish.toLowerCase(inputU)}\n");

var list = ["Az","ağ","aç","ad"];
print("Input= $list");
print("Default Sort= ${list..sort()}");

list = ["Az","ağ","aç","ad"];
print("Turkish Sort= ${list..sort(turkish.comparator)}");

list = ["Az","ağ","aç","ad"];
print("Turkish Sort Ignore Case= ${list..sort(turkish.comparatorIgnoreCase)}");

UpperCase for [kısa şiir]
Default= KISA ŞIIR, Turkish=KISA ŞİİR

LowerCase for [KISA ŞİİR]
Default= kisa şiir, Turkish=kısa şiir

Input= [Az, ağ, aç, ad]
Default Sort= [Az, ad, aç, ağ]
Turkish Sort= [Az, aç, ad, ağ]
Turkish Sort Ignore Case= [aç, ad, ağ, Az]


  • Fix homepage in pub.yaml


  • Initial version, converted from dotless_i project.
  • Make it Dart2 compatible.
  • Add letters with circumflex to sorting mechanism.


import 'package:turkish/turkish.dart';

main() {
  // upperCaseTr
  var inputL = "kısa şiir";
  print("UpperCase for [$inputL]");
  print("Default= ${inputL.toUpperCase()}, "

  // lowerCaseTr
  var inputU = "KISA ŞİİR";
  print("LowerCase for [$inputU]");
  print("Default= ${inputU.toLowerCase()}, "

  // sort Default
  var list = ["Az", "ağ", "aç", "ad"];
  print("Input= $list");
  print("Default Sort= ${list..sort()}");

  // sort Turkish  
  list = ["Az", "ağ", "aç", "ad"];
  print("Turkish Sort= ${list..sort(turkish.comparator)}");

  // sort Turkish ignore case  
  list = ["Az", "ağ", "aç", "ad"];
  print("Turkish Sort Ignore Case= "

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.
