question: How to add a custom 404 page(Route not found page).

[Luckey-Elijah]

you can create a wildcard route routes/[...not_found].dart

// routes/[...not_found].dart
import 'dart:io';

import 'package:dart_frog/dart_frog.dart';

Response onRequest(RequestContext context, String page) {
  return Response(body: '$page not found!', statusCode: HttpStatus.notFound);
}
