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,
) {
  context.addMethodInvocation((MethodInvocation node) {
    if (!_geocodingMethods.contains(node.methodName.name)) return;

    // Check if there's a cache lookup nearby in the enclosing function
    AstNode? current = node.parent;
    while (current != null) {
      if (current is FunctionBody) {
        final String bodySource = current.toSource();
        // Look for cache patterns
        if (RegExp(r'\bcache\b').hasMatch(bodySource) ||
            RegExp(r'\bCache\b').hasMatch(bodySource) ||
            RegExp(r'_geocode').hasMatch(bodySource) ||
            RegExp(r'_placemark').hasMatch(bodySource) ||
            RegExp(r'\bcached\b').hasMatch(bodySource)) {
          return; // Has cache, OK
        }
        break;
      }
      current = current.parent;
    }

    reporter.atNode(node);
  });
}
