How to Capitalized each first letter for a Sentence in Flutter...?

Question

I want to capitalize each first letter from a sentence for Flutter..??

This is a capitalized sentence I'm expecting from This Is A Capitalized Sentence

Answer 1

extension StringExtension on String {
  String capitalizeByWord() {
    if (trim().isEmpty) {
      return '';
    }
    return split(' ')
        .map((element) =>
            "${element[0].toUpperCase()}${element.substring(1).toLowerCase()}")
        .join(" ");
  }
}

Use extension like this. So that you can use capitalizeByWord on any String to convert it.

void main() async {
  var data = 'this is a capitalized sentence';
  print(data.capitalizeByWord()); // This prints the result 'This Is A Capitalized Sentence'
}
