isValidValue method

bool isValidValue(String value)

Validates if the given value is allowed for this parameter

For enum parameters, validates against the allowed values list

• For boolean types: accepts any valid boolean ('true' or 'false') regardless of values list
• For string types: case-insensitive string comparison (quotes are stripped)
• For numeric types (int/double): numeric equivalence (e.g., "3.0" == "3" for int) For non-enum parameters, always returns true

Implementation

bool isValidValue(String value) {
  if (!isEnum) return true;

  // For boolean types, always accept 'true' or 'false' regardless of values list
  // When type is explicitly boolean, the values list is just for documentation/picker purposes
  if (type == 'boolean' || type == 'bool') {
    final lowerValue = value.toLowerCase();
    return lowerValue == 'true' || lowerValue == 'false';
  }

  // For numeric types, compare numeric values
  if (type == 'integer' || type == 'double') {
    final valueNum = double.tryParse(value);
    if (valueNum == null) return false;

    return values!.any((v) {
      final enumNum = double.tryParse(v);
      if (enumNum == null) return false;
      return valueNum == enumNum;
    });
  }

  // For string types, use case-insensitive string comparison
  // Strip quotes from enum values for comparison (quotes are preserved in YAML to
  // distinguish strings from booleans, but should be ignored when matching input)
  final lowerValue = value.toLowerCase();
  return values!.any((v) => _stripQuotes(v).toLowerCase() == lowerValue);
