static void exposeDiagnosticsTree(Outgoing outgoing, String name) {
  Inspect()
    ..serve(outgoing)
    ..onDemand(name, (Node inspectMountRoot) {
      var diagnosticsRoot =
          WidgetsBinding.instance.renderViewElement!.toDiagnosticsNode();
      inspectFromDiagnostic(diagnosticsRoot, inspectMountRoot);
    });
}
