runWithReporter method

  1. @override
void runWithReporter(
  1. SaropaDiagnosticReporter reporter,
  2. SaropaContext context
)
override

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.addMethodDeclaration((MethodDeclaration node) {
    // Must be an async method returning Future
    if (!node.isAbstract && node.body is! BlockFunctionBody) return;
    final FunctionBody body = node.body;
    if (body is! BlockFunctionBody) return;

    final String bodySource = body.toSource();

    if (!_cacheBodyRegex.any((re) => re.hasMatch(bodySource))) return;
    if (!RegExp(r'\bawait\b').hasMatch(bodySource)) return;

    // Check for in-flight dedup or lock patterns (suppression)
    if (_hasDeduplication(bodySource, node)) return;

    // Look for the cache-miss-then-await pattern
    if (_hasCacheMissThenAwait(body.block)) {
      reporter.atToken(node.name, code);
    }
  });
