RegexValidator class

Validates strings against a regular expression pattern.

This validator uses regular expressions to validate string format, making it perfect for emails, URLs, phone numbers, and custom formats.

Example:

// Email validation
final emailValidator = RegexValidator(
  r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$',
  description: 'Must be a valid email address',
);

// Hexadecimal color code
final hexColorValidator = RegexValidator(
  r'^#[0-9A-Fa-f]{6}$',
  description: 'Must be a valid hex color code (e.g., #FF0000)',
);
