runWithReporter method

@override void runWithReporter(SaropaDiagnosticReporter reporter, SaropaContext context)

Override this method to implement your lint rule.

Use context to register callbacks for AST node types:

context.addMethodInvocation((node) {
  if (condition) {
    reporter.atNode(node);
  }
});

Implementation

@override
void runWithReporter(
  SaropaDiagnosticReporter reporter,
  SaropaContext context,
) {
  // This is a simplified version - full implementation would track
  // all call sites across the codebase
  context.addFunctionDeclaration((FunctionDeclaration node) {
    final FormalParameterList? params = node.functionExpression.parameters;
    if (params == null) return;

    for (final FormalParameter param in params.parameters) {
      // Check if parameter type is nullable
      TypeAnnotation? type;
      if (param is RegularFormalParameter &&
          param.functionTypedSuffix == null) {
        type = param.type;
      }

      if (type == null) continue;

      // Check if nullable
      if (type.question != null) {
        // This is a simplified heuristic
        // Full implementation would analyze call sites
      }
    }
  });
