void main() {
  String str = "Hello, world!";
  
  // Converting the string to uppercase
  String uppercaseStr = str.toUpperCase();
  print("Uppercase string: $uppercaseStr");
  
  // Checking if the string starts with a specific substring
  String prefix = "Hello";
  bool startsWithHello = str.startsWith(prefix);
  print("Starts with 'Hello': $startsWithHello");
  
  // Getting the length of the string
  int length = str.length;
  print("Length of string: $length");
  
  // Extracting a portion of the string
  String substring = str.substring(7, 12);
  print("Substring: $substring");
  
  // Finding the index of a specific character in the string
  int indexOfComma = str.indexOf(",");
  print("Index of comma: $indexOfComma");
}
