How to replace letters with accents for the same ones without an accent?

  • 772

I am trying to carry out an ordering method based on certain criteria, one of them is by the first letter with which a title begins. But I run into the accents which I don't know how to evaluate with a regular expression.

For my ordering method, I first remove any title that contains a character at the beginning that is not a letter or a number.

The titles are already sorted from a query with SQLiteusing theORDER BY

if (titulo.contains(RegExp(r'^\W'))) {
    print(titulo);
}

Which also prints those that start with an accent ,

I/flutter (12242): ¡Cuánto me ama ! 
I/flutter (12242): Él corazón 
I/flutter (12242): Óyenos

Try doing what they suggest in the following answer . but i can't get it to work

regex

    Luckily there is already a package that does all the work, it's called diacritic, you can find it here: https://pub.dev/packages/diacritic#-readme-tab-

    And if you want to see how many regular expressions it uses, just check the source code: https://github.com/agilord/diacritic/blob/master/lib/src/replacement_map.dart

    After that, the use is simple, you add it in pubspec.yamland here is an example of use:

    import 'package:diacritic/diacritic.dart';

    print(removeDiacritics('¡Cuánto me ama !'));
    print(removeDiacritics('Él corazón '));
    print(removeDiacritics('Óyenos'));

    Result

    flutter: ¡Cuanto me ama !
flutter: El corazon
flutter: Oyenos
