SafePasswordValidator class

A validator for ensuring password strength and security requirements.

SafePasswordValidator checks passwords against common security criteria: digits, lowercase letters, uppercase letters, and special characters. Each requirement can be individually enabled or disabled.

Example:

SafePasswordValidator(
  requireDigit: true,
  requireLowercase: true,
  requireUppercase: true,
  requireSpecialChar: true,
  message: 'Password must meet security requirements',
)
