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 (node.methodName.name != 'listen') return;

    final Expression? target = node.target;
    if (target == null) return;

    final String targetSource = target.toSource();
    if (!targetSource.endsWith('socket') &&
        !targetSource.endsWith('Socket') &&
        !targetSource.endsWith('channel') &&
        !targetSource.endsWith('Channel')) {
      return;
    }

    final ArgumentList args = node.argumentList;
    if (args.arguments.isEmpty) return;

    final Expression firstArg = args.arguments.first;
    if (firstArg is! FunctionExpression) return;

    final String bodySource = firstArg.body.toSource();
    if (_validationBodyPatterns.any((p) => p.hasMatch(bodySource))) {
      return;
    }

    reporter.atNode(node);
  });
}
