@override int get arity

Implementation

@override
int get arity {
  if (isSetter) return 1; // Setters always take one argument
  // Original logic for required positional parameters
  final params = _parameters?.parameters;
  if (params == null) return 0;
  return params
      .where((p) =>
          p is SSimpleFormalParameter ||
          p is SFieldFormalParameter ||
          p is SFunctionTypedFormalParameter ||
          p is SSuperFormalParameter)
      .where((p) {
    if (p is SSimpleFormalParameter) return p.isPositional && p.isRequired;
    return true; // Other NormalFormalParameter-like types are required positional by default
  }).length;
