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,
) {
  // File-level check: collect ALL method invocations across the compilation
  // unit in a single pass, then decide once per file whether to report.
  context.addCompilationUnit((CompilationUnit unit) {
    // Import guard — only applies to files that import receive_sharing_intent.
    // fileImportsPackage requires an AstNode; the beginToken's parent is the
    // unit itself, so pass the unit directly.
    if (!fileImportsPackage(unit, PackageImports.receiveSharingIntent)) {
      return;
    }

    final _MethodNameCollector collector = _MethodNameCollector();
    unit.accept(collector);

    // No getMediaStream calls — nothing to report.
    if (collector.getMediaStreamCalls.isEmpty) return;

    // Both paths wired — compliant.
    if (collector.getInitialMediaCalls.isNotEmpty) return;

    // Report at the first getMediaStream call site so the diagnostic lands on
    // the call that is "missing its partner" rather than on the file header.
    reporter.atNode(collector.getMediaStreamCalls.first.methodName);
  });
