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.addConditionalExpression((ConditionalExpression node) {
    // Check for nested ternary operators
    if (node.thenExpression is ConditionalExpression ||
        node.elseExpression is ConditionalExpression) {
      reporter.atNode(node);
    }
  });

  context.addCascadeExpression((CascadeExpression node) {
    // Check for nested cascades
    for (final Expression section in node.cascadeSections) {
      if (section is CascadeExpression) {
        reporter.atNode(section);
      }
    }
  });

  context.addBinaryExpression((BinaryExpression node) {
    // Check for nested null-aware operators
    if (node.operator.lexeme == '??') {
      if (node.rightOperand case BinaryExpression right) {
        if (right.operator.lexeme == '??') {
          reporter.atNode(node);
        }
      }
    }
  });
