validateAppBarElevation function

double validateAppBarElevation(

  2. required double defaultValue,
  3. bool? enableSecurity,
})

Validate elevation is within bounds. Pass enableSecurity to override global setting, or leave null to use global.

Implementation

double validateAppBarElevation(
  double? value, {
  required double defaultValue,
  bool? enableSecurity,
}) {
  if (value == null) return defaultValue;
  final shouldValidate =
      enableSecurity ?? AppBarSecurityConfig.enforceValidation;
  if (!shouldValidate) return value;

  if (value < 0) {
    _logAppBarSecurity('Elevation $value is negative, using 0');
    return 0;
  }

  if (value > AppBarSecurityConfig.maxElevation) {
    _logAppBarSecurity(
      'Elevation $value above maximum ${AppBarSecurityConfig.maxElevation}',
    );
    return AppBarSecurityConfig.maxElevation;
  }

  return value;
}
