Converts a string to kebab case.

Use String.replaceAllMapped() to break the string into words and String.toLowerCase() to convert each one to lowercase, using a RegExp.
Use String.replaceAll() to replace invalid separator characters (_ and spaces). with hyphens

代码实现

String toKebabCase(String str) {
  return str
      .replaceAllMapped(
          RegExp(
            r'[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+'),
          (Match m) => "${m[0].toLowerCase()}")
      .replaceAll(RegExp(r'(_|\s)+'), '-');
}

使用样例

toKebabCase('camelCase'); // 'camel-case'
toKebabCase('some text'); // 'some-text'
toKebabCase('some-mixed_string With spaces_underscores-and-hyphens'); // 'some-mixed-string-with-spaces-underscores-and-hyphens'
