Usage

// Create successful validation result
final success = ValidationResult.success();

// Create failed validation result
final failure = ValidationResult.failure(['Invalid email format']);

// Create result with warnings
final withWarnings = ValidationResult.withWarnings(['Price seems high']);

// Check validation status
if (result.isValid) {
  // Proceed with valid data
} else {
  // Handle validation errors
  for (final error in result.errors) {
    print('Error: $error');
  }
