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.addClassDeclaration((ClassDeclaration node) {
    final ExtendsClause? extendsClause = node.extendsClause;
    if (extendsClause == null) return;

    final String superName = extendsClause.superclass.name.lexeme;

    // Check if this class extends something that ends with Event
    // but this class itself doesn't end with Event
    if (superName.endsWith('Event')) {
      final String className = node.nameToken.lexeme;
      if (!className.endsWith('Event')) {
        reporter.atNode(node);
      }
    }
  });
}
