validateTextShadows function

List<Shadow>? validateTextShadows(List<Shadow>? shadows, { bool? enableSecurity, })

Validates and limits shadow list.

Implementation

List<Shadow>? validateTextShadows(
  List<Shadow>? shadows, {
  bool? enableSecurity,
}) {
  final shouldValidate = enableSecurity ?? TextSecurityConfig.enforceValidation;

  if (shadows == null || shadows.isEmpty) return shadows;
  if (!shouldValidate) return shadows;

  if (shadows.length > TextSecurityConfig.maxShadowCount) {
    if (TextSecurityConfig.enableSecurityLogging) {
      debugPrint(
        '[SAC Text Security] Shadow count ${shadows.length} above max ${TextSecurityConfig.maxShadowCount}',
      );
    }
    shadows = shadows.take(TextSecurityConfig.maxShadowCount).toList();
  }

  return shadows.map((shadow) {
    double blurRadius = shadow.blurRadius;
    if (blurRadius > TextSecurityConfig.maxShadowBlurRadius) {
      if (TextSecurityConfig.enableSecurityLogging) {
        debugPrint(
          '[SAC Text Security] Shadow blur radius $blurRadius above max ${TextSecurityConfig.maxShadowBlurRadius}',
        );
      }
      blurRadius = TextSecurityConfig.maxShadowBlurRadius;
    }
    return Shadow(
      color: shadow.color,
      offset: shadow.offset,
      blurRadius: blurRadius,
    );
  }).toList();
