void main() {
	var hello = 'Hello, 🌍!';

	print(hello.toLowerCase());  // Output: "hello, 🌍!"

  hello = '  Hello, 🌍!  ';
	print(hello.trim());  // Output: "Hello, 🌍!"

  hello = 'Hello, 🌍!';
	print(hello.startsWith('Hell'));  // Output: true

  hello = 'Hello, 🌍!';
	print(hello.endsWith('🌍!'));  // Output: true

  hello = 'Hello, 🌍!';
	print(hello.contains('lo'));  // Output: true

  hello = 'Hello, 🌍!';
	print(hello.substring(0, 5));  // Output: "Hello"

  hello = 'Hello, 🌍!';
	print(hello.replaceFirst('Hello', 'Hi'));  // Output: "Hi, 🌍!"

  hello = 'Hello, Hello, 🌍!';
	print(hello.replaceAll('Hello', 'Hi'));  // Output: "Hi, Hi, 🌍!"

  hello = 'Hello, 🌍!';
	print(hello.split(', '));  // Output: ['Hello', '🌍!']

  List<String> helloList = ['Hello', '🌍!'];
	print(helloList.join());  // Output: Hello🌍!

  hello = 'Hello, 🌍!';
	print(hello.length);  // Output: 11
