如何在Dart中按多个分隔符拆分字符串

import 'dart:core';

void main() {
  String str = 'Hello, World!-This_is_a_sample_string';
  List<String> result = splitString(str, [',', '-', '_']);
  print(result);
}

List<String> splitString(String str, List<String> delimiters) {
  String pattern = delimiters.map((delimiter) => delimiter.replaceAll(RegExp(r'[^\w\s]'), '\\$&')).join('|');
  RegExp regex = RegExp(pattern);
  return str.split(regex);
}
