StringUtils class

StringUtils is a utility class in Dart that provides static methods for manipulating and analyzing strings. This class cannot be instantiated.

The methods in this class include, but are not limited to, methods for checking string equality, converting strings to different cases, checking if a string is empty or null, and so on.

Example usage:

String str = 'Hello, World!';
bool isEmpty = StringUtils.isEmpty(str);  // returns false
String upper = StringUtils.toUpperCase(str);  // returns 'HELLO, WORLD!'

Note: All methods in this class are null-safe, meaning they will not throw an exception if the input string is null. Instead, they will return a reasonable default value (usually null or false, depending on the method).
