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 (!_isHomeWidgetCall(node, const <String>{'saveWidgetData'})) return;
    if (!fileImportsPackage(node, PackageImports.homeWidget)) return;

    final FunctionBody? body = _enclosingMemberBody(node);
    if (body == null) return;

    final _HomeWidgetScan scan = _HomeWidgetScan();
    body.accept(scan);

    final bool hasUpdate = scan.invocations.any(
      (MethodInvocation inv) =>
          _isHomeWidgetCall(inv, const <String>{'updateWidget'}),
    );
    if (hasUpdate) return;

    reporter.atNode(node);
  });
}
