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.addInstanceCreationExpression((InstanceCreationExpression node) {
    final String? typeName = node.constructorName.type.element?.name;
    if (typeName == null || !_animatedWidgets.contains(typeName)) return;

    // Check if wrapped in RepaintBoundary
    AstNode? current = node.parent;
    int depth = 0;
    bool hasRepaintBoundary = false;

    while (current != null && depth < 5) {
      if (current is InstanceCreationExpression) {
        final String? parentType = current.constructorName.type.element?.name;
        if (parentType == 'RepaintBoundary') {
          hasRepaintBoundary = true;
          break;
        }
      }
      current = current.parent;
      depth++;
    }

    // Only report if inside Stack or complex layout (where isolation matters)
    if (!hasRepaintBoundary) {
      AstNode? parent = node.parent;
      while (parent != null) {
        if (parent is InstanceCreationExpression) {
          final String? parentType =
              parent.constructorName.type.element?.name;
          if (parentType == 'Stack' ||
              parentType == 'CustomMultiChildLayout') {
            reporter.atNode(node.constructorName, code);
            return;
          }
